The Lone Rangers and Wyld Stallyns vs. Spinal Tap
Movie band fight.
Wild Stallyns (from Bill and Ted's Excellent Adventure) and The Lone Rangers (from Airheads) are about to do a set in the local club when Spinal Tap emerges onstage and demands that they not play because they suck, and should let a real band play for the audience.
Nigel Tufnel: Get off of the stage or we'll stuff your trousers full of armadillos!
Bill: Dude....
Ted: Bogus....
Pip: Eat shit! I'll stab out your eyes with my dick!
Chazz: You greasy Brits got some balls.
Rex: Not for long, they don't.
Ian Faith: Certainly, in the topsy-turvy world of heavy rock, having a good solid piece of wood in your hand is often useful.
Rex: Up your ass, pal!
The fight takes place onstage. All the regular instruments are available for melee.
