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!").

Now is the winter of our discontent made glorious summer by this son of York, who joineth me in not wearing any pants.

Stevie

Come again:
Sweet love doth now invite
Thy graces that refrain
From wearing any pants

I teleported home one day
With Ron and Sid and Nance
Ron stole Nancy's heart away
And I'm not wearing pants -- Douglas Adams (almost)

The Dude abides. I don't know about you but I take comfort in that. It's good knowin' he's out there. The Dude. Takin' 'er easy for all us sinners. Shoosh. I sure hope he's not wearing any pants.

Stevie

I am unable to come to the phone right now, because I'm not wearing any pants. I'm absolutely changing my outgoing message to this.

My God! It's not wearing any pants!

O CAPTAIN! my Captain! our fearful trip is done;
The ship has weather’d every rack, the prize we sought is won;
The port is near, the bells I hear, the people all exulting,
While follow eyes the steady keel, the vessel grim and daring:
  But O heart! heart! heart!
    O the bleeding drops of red,
      Where on the deck my Captain lies,
        Not wearing any pants.
