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!").

[Raak] Splendid!

I've never seen you looking so lovely as you did tonight,
I've never seen you shine so bright,
I've never seen so many men ask you if you wanted to dance,
They're looking for a little romance, not wearing any pants

Vader: If only you knew the power of the Dark Side. Obi-Wan never told you what happened to your father.
Skywalker: He told me enough! He told me you stole his pants!
Vader: No, I am not wearing any pants.
Skywalker: [shocked] No. No! That's not true! That's impossible!
Vader: Search your feelings; you know it to be true!
Skywalker: NOOOOOOO! NOOOOOOOO!!!
