One day in 1984, Red Hot Chili Peppers frontman Anthony Kiedis and Peppers bassist Flea took a break during a long recording session to visit the bathroom. "Don't trouble me by bringing it back, right?" joked British producer Andy Gill. Sure enough, the lads returned a few minutes later with the band's newest member. Gill's verdict of the specimen? "Typical."

[Kiedis and Flea were class clowns in high school. Among their favorite pranks? Climbing billboards and flashing passing motorists.]
