And if you won't undress to mate me,
I won't undress to mate you.

The story:

I had quoted the real lyrics to a friend when we were discussing how people don't give each other a break. He looked at me, asking what the heck this song had to do with it. I explained, and he said, "Oh! I thought you said, "If you won't undress to mate me, I won't undress to mate you."

"Paul," I said, "Is there something you want to tell me?"
