mc5 - I'm not wearing any pants!

Take a familiar (or at least famous) quote (e.g. "Don't go around saying the world owes you a living. The world owes you nothing. It was here first." by Mark Twain). Then find a good stopping point (e.g. "Don't go around saying"). After this, add the phrase, "I'm not wearing any pants (e.g. ""Don't go around saying, "I'm not wearing any pants!").

For it's dark as a dungeon and damp as the dew
Where the dangers are doubled and the pleasures are few
Where the rain never falls and the sun has no chance
And the bloody shift foreman's not wearing his pants.

Stevie

Hey Joe, why're you not wearin' any pants?

Stevie

Sixteen men with a pirate stance
Yo-ho-ho and a bottle of rum
Not a man jack of them wearing any pants
Yo-ho-ho and a bottle of rum

There was a young fellow from Hants.

nicely played above. *chuckling*
Richard is soon unhorsed on the field at the climax of the battle, and cries out, "A horse, a horse, my kingdom for a pair of pants!"
