Another one I came across. Son told me other one.
A husband exclaims to his wife one day, "Your butt is getting really big. It's bigger than the BBQ grill!" Later that night in bed, the husband makes some advances towards his wife who completely brushes him off. "What's wrong?" he asks. She answers, "Do you really think I'm going to fire up this big-@ss grill for one little weenie?"
