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!").

...and now class: to demonstrate Newton's Third Law, I am not wearing any pants.

I know what you're thinking, punk. You're thinking "did he fire six shots or only five?" Now to tell you the truth I forgot myself in all this excitement. But being this is a .44 Magnum, the most powerful handgun in the world and will blow your head clean off, you've gotta ask yourself a question: "Why ain't that cop wearing any pants?"

Pooh

In Dixie Land where I was born in,
Early on one frosty mornin,
Look away! Look away! Look away! Sheesh! I ain't wearin' no pants.

Salt? Vinegar? Pants?

No sun - no moon!
No morn - no noon -
No dawn - no dusk - no proper time of day.
No warmth, no cheerfulness, no healthful ease,
No comfortable feel in any member -
No shade, no shine, no butterflies, no bees,
No fruits, no flowers, no leaves, no birds! -
No pants!
