...that did the pushin'
Left the stains upon the cushion
Footprints on the dashboard upside down?

If it was you, you sly woodpecker
That got into my daughter Rebecca
I think you better leave this town.

The answer
Yes was I that did the pushin'
Left the stains upon the cushion
Footprints on the dashboard upside down.

But since I got into your daughter
I've had problems passing water
So I think we're even all around.

An old joke, but fun if you know the melody.  Thanks to John Valby.
