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!").

*ahem*

[Stevie] GUFFAW ..... It is difficult to keep one's head when all about you are wearing no pants.

A holiday, A holiday and the first one of the year
Lord Donal's wife to church did go The Gospel for to hear
And when the meeting it was done she looked about askance
And there she saw little Matty Groves not wearing any pants

[Stevie] Was that the incident that inspired the Andy Stewart song "Donald, where's your trousers?"

I've already told the story in another place in which a pair of Birmingham constables, confronting my friend at a particularly trying juncture in his stag night and threatening to run him in for being drunk and disorderly were tersely informed "I'm not drunk and I'm certainly not disorderly. I just haven't got any trousers on".
