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!").

Colour Sergeant Bourne! Take three sections and form a flying platoon! And for God's sake put on your pants!

Stevie

You think you lost your love
Well I saw her in Northants
It's you she's thinking of
Not wearing any pants

Stevie

Let the wind blow high
Let the wind blow low
Through the street in a kilt I'll go
All the lassies say 'Hullo!'
'Donald where's your troohaaaaaang on a minute.

Stevie

Double, double, toil and trouble
Fire burn and cauldron bubble
Eyes of newts and legs of ants
Macbeth's not wearing any pants

W Churchill

We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills, even when we're not wearing any pants.
