Most Unusual and Funny Story

I asked a guy if he wanted to know anything about his bellybutton.

He assured me he knew everything he wanted to know.

Then he said, "I used to collect my bellybutton lint.  I'd save it in a cup on the top of the fridge.  When my girlfriend came over for the first time, she found it and asked what it was.  I asked her to guess. She did.  And she was right."

They are now married.
