Opening for Madonna on one of her earlier tours. The interaction between the fanbases was...interesting.
The short film for "Don't Play No Game That I Can't Win" with Santigold certainly qualifies. A marionette adventure! The plot of the video is: the Marionette!Beasties are pursued by a Determinator unnamed commando who is inexplicably anti-Beasties. The commando ambushes the Beasties at a concert, who promptly escape into a snowy forest. The commando and his troops attack the Beasties; all but the commando are killed. The dead troops return as zombies to come after the Beasties, who are unexpectedly rescued by a Yeti. The Yeti flies the Beasties off by helicopter, which is then shot down by the commando. The Beasties parachute safely into an ocean. Mike D is then attacked by a shark, but rescued by the return of Santigold, who was on stage during the concert at the beginning. The Beasties and Santigold, inside a submersible, then take out the commando and his next wave of troops by firing missiles at them. As the Beasties and Santigold escape, the commando emerges from the water, still bent on revenge.
In "No Sleep Till' Brooklyn", when the guitar solo begins, a guy in a gorilla suit is shown playing it, only for a more metal looking guitarist to rush in, shoulder push the gorilla away and resume the solo. That guitarist, Kerry King fromSlayer.
Even funnier was that originally Kerry and the gorilla's roles were reversed, but Kerry objected, saying "If anyone is gonna is gonna be pushed off stage, it's gonna be me pushing the gorilla."
Misaimed Fandom: While a lot of their songs (especially their earlier material) were meant as a parody, quite a few people wound up taking them seriously. For example, "(You Gotta) Fight For Your Right (To Party!)" was meant as a spoof of party songs but ironically became a big hit among the people they were making fun of.
Signature Song: Originally "Fight For Your Right", now it's probably "Sabotage" and "Intergalactic".
Some Anvils Need to Be Dropped: The "Fight For Your Right Revisited" video is sort of a very late subtle apology for their early days. In the video, the past Beastie Boys, all played by actors, are confronted by what would be the future versions of themselves if they had stayed the same. The Future!Beasties are played by separate actors. Prior to this, the Past!Beasties had gone on a drunken rampage with loads of Hey, It's That Guy! in between. When Future!Beasties challenge Past!Beasties to a dance-off, the Future!Beasties end it quickly with a literal pissing contest before all the Beasties are hauled off by cops (played by the real Beasties).
