6. Billy Idol In The Wedding Singer Alright I promise this will be the last musician appearance on this list but when Billy Idol is saving the day, you can't not include him. Adam Sandler's wedding singer character is unknowingly on the same flight as the girl he loves as well as her irredeemable douchebag of a fiance. With the help of Billy Idol, Sandler is able to serenade Drew Barrymore, win her back and eventually live happily ever after - and who says punk music had no positive lasting legacy?!
5. Bob Barker In Happy Gilmore
Yet another Adam Sandler movie, Happy Gilmore is about a wannabe hockey player who ends up in the world of professional golf. At a doubles tournament he gets paired with Bob Barker. However, Happy can't concentrate because of a heckler in the crowd, hired by the villain of the piece for that very reason, and his poor performance angers Barker, which leads them to a fierce bout of hilarious fisticuffs. They fight all over the green and just when it seems as if Happy won, Bob Barker rises and knocks out the manchild, offer a delightful opportunity for Barker to break expectations of his persona in one gloriously effective sign-off.
