The Cameo: Winding down their performance at the high school dance, lead singer Dexter Holland is scalped by the evil severed hand.

The Cameo: He pops up as a Philadelphia pawn broker targeted by Louis Winthorpe III (Dan Aykroyd), whom he believes is attempting to sell him a stolen watch.

Ozzy Osbourne - Trick Or Treat (1986)
The Musician: Frontman singer of British metal legends Black Sabbath.
The Cameo: Ozzy is barely recognisable as a straight-laced televangelist, rallying against the evil depravity found in rock music and the terrible influence it has on young, impressionable minds.

Chris Cornell - Singles (1992)
The Musician: The lead singer and guitarist for seminal Seattle rockers Soundgarden.
The Cameo: Cliff (Matt Dillon) tries to impress Janet (Bridget Fonda) by installing her a new car stereo and blasting it at full volume, attracting the neighbours... including a beautifully-coiffed Cornell.

Lemmy - Airheads (1994)
The Musician: The mutton chop-wearing lead singer and bassist for 80s metal stalwarts, Motorhead.
The Cameo: As the crowd outside the radio station shout out embarrassingly nerdy exploits from their pasts, Lemmy pops up briefly and yells I was editor of the school magazine!
Geekiest Fact: His one line is actually true: Lemmy really did edit his school magazine.
Snoop Dogg - Half-Baked (1998)
The Musician: Rapper, singer, songwriter, Snoop Dogg was one of the original West Coast hip hop artists to emerge in the early 90s.
The Cameo: In his 60-second role, Snoop Dogg appears as if from nowhere as an example of a Scavenger Smoker (a person who only ever partakes in another mans weed).
Geekiest Fact: The perfect execution of the long toke could be attributed to his personal possession of a medical marijuana license. And the fact hes built an entire image around his heavy smoking habits.
Alice Cooper - Prince of Darkness (1987)
The Musician: Singer for hair metal schlockers, Alice Cooper, the man has nary left one corner of the rock genre unturned.
The Cameo: A homeless street bum, Coopers character indulges in a brief, bloody murder to the strains of one of his own songs...
