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!").

Not a man jack of them wearing any pants
Yo-ho-ho and a bottle of rum

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!"

Shall I compare thee to a summer's day?
While I'm not wearing any pants?
