Here are different references found in BASEketball.  There are also a few references of BASEketball found in other movies.  Also find secrets, DYNs, and bloopers found in the movie.  Secrets are found here.  Bloopers are found right nyahh and nyahh.

2. The second scene involves President Harris trying to blast his way out of the White House. Agent Johnson blasts a hole through Mother Teresa's picture and through the wall behind it. He and Harris then crawl out. Johnson says, "God, this is exciting!" Harris responds with "This is exciting? You should feel my nipples." In Baseketball Costas and Michaels are calling the Denslow Cup V final game. Michaels says, "Bob, in all my years of calling games I don't think I've ever been this excited!" Costas replies with "You're excited? Feel these nipples!"

3. The funeral wake scene involves George, and then Mahalik, trying to bring Brenda back to life rather vigorously. Mahalik pounds on Brenda's chest and screams "Live, damnit! Live!!" George providing some live wires for heart paddles, electrocuting Mahalik and the man trying to pull him off Brenda's corpse. This is similar to the hospital scene in Baseketball, where Coop and Remer try to save Joey from dying. That scene involved Coop trying to keep Joey alive rather vigorously. Coop jumps on top of Joey, begins pounding on his chest, and screams "Live, damnit! Live!!" Later on, Coop uses some heart paddles on Joey. Once Remer sets the voltage at 15,000 volts, Squeak is electrocuted and thrown off Joey.

4. There was the scene in the video itself where a chair spun in the air upside down. A fat man somehow sat in that chair and so spun with the chair. Then he got off and puked into a small ice bucket. In Basketball, during a game in which Coop is drafted to make three homers for Joey, Remer and Squeak puked into small ice buckets after a night of heavy drinking. Coop plays drunk throughout the game and misses the third homer.

5. The aliens looked similar to the ones dancing around in Baseketball -- crappy costumes and all -- on "anal probe night." - (above text thanks to Will, over at the South Park Scriptorium.)

              6. Jenny McCarthy was cast in both movies.

     1. During Denslow's will reading, in the very beginning, he says, "...these chaps I wore in Rootin' Tootin" Rhythm I bequeath to my nephew Herman..."

    1. During the whole bar scene with Coop, Remer, and Joey, they were watching the Jerry Springer show.

     1. When the Beers play the Roswell Aliens at Roswell Stadium, Al Michaels says, "...from the 15,000 on here for Anal Probe Night."  This refers to the first episode of South Park, Cartman Gets an Anal Probe.

     2. In the locker room scene, Coop says, "Oh, sorry I forgot how much Doug Remer cares about kids."  He says that in the voice of the boy's teacher, Mr. Garrison.

     3. Coop's psyche-out at the end of the movie, to psyche-out Grunsky, was done in Eric Cartman's voice.

References to BASEketball
     1. In BASEketball, Jenna is reading Women Who Run with the Wolves, during the hospital scene where Coop brings La-Z-Boy.  In South Park episode 316 Are You There God?  It's Me, Jesus, Cartman is reading the same book during one of the boy's meetings in the treehouse.

     2. Yasmine Bleeth makes an appearance in episode 511, The Entity.  You see her getting out of a junky car and wiping her nose.  Needless to say Matt and Trey probably wouldn't have shown her if they weren't cast members in BASEketball.

    3. In  804 The Passion of the Jew, aired March 31st, Stan and Kenny want their money back from seeing the Passion.  Here's the scenes dialogue:

Stan: [packing] Come on, Kenny, we're going to Malibu! 
Kenny: (Malibu? But how?) 
Stan: We'll take the bus! Look, this isn't about the eighteen dollars ticket money anymore. This is about being able to hold bad filmmakers responsible! [He leads Kenny out of his room] This is just like when we got our money back for BASEketball!

     4. In "Free Hat", the boys dress up in island clothing to warm George Lucas' icy heart.  This clothing is almost exactly the same as the clothing worn by Coop and Remer while on the Malakalaka Balance Board of Trust.  Also, the boys' dance is very similar to Coop and Remer's island dance in a deleted scene.

     1. After Coop left for Calcutta, he was presumed as "missing".  Robert Stack, the host of Unsolved Mysteries, covered the case.

     1. At the end of the movie, Squeak shouts, "I'm the king of the world!", while atop the Denslow Cup.  Jack did the same in the scene where he was leaning over the bow of the boat, in Titanic.

     2.  Right before the make-out scene, when Coop and Remer were about to fall off the Malaka-Laka board, Coop shouts, "Remember to hold your breath just before we hit!  Never let go!  This dialogue is taken from Titanic.  (Thanks to Lisa8476 from the South Park Studios BBS, via e-mail.)

     1. The scene where Dan Patrick and Kenny Mayne are talking about the playoffs is a direct copy of their real show, SportsCenter.

Foster's Beer Commercials

     1. During the San Fransisco game, Coop says "How to speak San Fransiscan...(pulls down Squeak's pants, exposing his crack)...Vagoina!"  He says this in an Australian accent, and the line "How to speak Australian" is the catch-phrase for the Foster's Beer commercials.

The Horse Whisperer (1998)

     1. During the Beer's game against the Detroit Lemons, (during the scene with all the clips of games), Remer plays a tape.  The dialogue that follows is from the book, The Horse Whisperer, by Nick Evans.  This was made into a movie in 1998.

Braveheart (1995)

     1. After Squeak psyches-out Tuttle to end the game versus the L.A. Riots, the Riot's team members tie him up on the garage door.  He screams, "Freedom!  Freedom!"  This line is from Braveheart.

     2. During the hospital scene, where the Beers are trying to revive the living Joey, Coop says, "I love ya.  Always have."  Mel Gibson's character in Braveheart says the same lines.

Scarface (1983)

     1. Tony Montana mouths this sentence in Scarface, "In this country, you gotta make the money first. Then when you get the money, you get the power. Then when you get the power, then you get the women."  In BASEketball, right after Coop and Remer beat the preps at Britney's party, Coop says this: "Dude, I'm telling you it's jobs.  We gotta get jobs.  Then we get the khakis.  Then we get the chicks."  Different words, but reference indeed.

Brain Donors (1992)

     1. In Brain Donors, Lillian Oglethorpe says, "Then it's settled. I am so excited. Roland T. Flakfizer replies with, "You're excited? Feel these nipples."  In BASEketball, Al Michaels says, "Bob, in all my years of calling games, I don't think I've ever been this excited!, after the Beers win the Denslow Cup.  Bob Costas responds with, "You're excited?  Feel these nippples!"

Airplane! (1980)

     1. In BASEketball, during the hospital scene after the game, Coop and Remer go to comfort Joey after his operation.  They both sit on Joey's bed and cut off his oxygen supply.  In Airplane! the stewardess goes back to comfort the sick girl and inadvertantly cuts off her oxygen supply with her guitar.  The reaction of both kids is strikingly similar.

    2. Robert Stack (deceased) and Kareem Abdul-Jabaar make appearances in both Airplane! and BASEketball.  Seems to be one of the many trends of David Zucker movies.  (Both thanks to Lisa8476 from the South Park Studios BBS, via e-mail.)

Superosity (Online Comic Strip)

     1. BASEketball was mentioned in an online comic strip called Superosity.  Check it out here.  Brought up by Charlie_B on the South Park Studios BBS.

Dodgeball: A True Underdog Story (2004)

     1. There's not really any direct references to BASEketball, but the structure of both movies is very, very similar.  Here's a list of similarites.

• Crude Jokes, about sex and what not.
• Wacky team names.  (Kamikazes, M.I.L.F.S, etc)
• Evil rich guy that is on the rival team. (White Goodman and Baxter Cain)
• People hid in head and balls with balls.
• Main character/best player comes to the championship game just in time to help his team win the game. (Peter LeFleur and Joe Cooper)
• Everyone starting to make out after they win the championship
• Main characters have money issues. (Peter is challenged with a bribe and needs championship money for his gym.  Remer agrees to clothing deal, and the clothes are made by children in Calcutta.  Coop has to fix the child labor issue.)
• Both teams face uphill battles to keep their gym/team. (Average Joe's and the Beers.)
• Cheerleaders.  'Nuff said.
• Crazy announcers.
• Crucial games coming down to final moments.
• Celebrity cameos.  Lots and lots of celebrites.
• Computer generated game intros. (Denslow Cup title)

     1. Matt and Trey have conversations in Scottish accents in both BASEketball and their short lived unaired TV series, Time Warped.  It's in the hospital scene, and starts with Coop saying "Dammit man, I'm tryin to save an innocent life!".  Download the Time Warped clip here.

Cannibal! The Musical (1995)

     1.  I call this reference "Trey Can't Dance".  In Cannibal! The Musical, Trey uses a "stunt" double for the ballet scene.  (This is pretty obvious to notice.)  Not so obvious, but that mime psycheout in BASEketball was not done by Trey Parker.  That was also another "stunt" double.  Let's face it, Trey can't do those tough positions!

     1. 1.  At one point, Chris says, "Oh s***."  It is said the exact same way as Coop during the BASEketball game at Britney's

     2. When Gary is in the bar, the camera zooms to the jukebox to show that it is playing "Freedom Isn't Free".  This song reflects Gary's life and feelings at the time, much like "Warts on Your D***" reflected what Coop was going through
