A husband, thinking he was being funny, said to his wife, "Perhaps we should start washing your clothes in "Slim Fast". Maybe it would take a few inches off your butt!" 

The next morning the husband took a pair of underwear out of his drawer. "What the heck is this?" he said to himself as a little cloud appeared when he shook them out. 

He hollered into the bathroom," Why did you put talcum powder in my underwear?" 

 She replied "It's not talcum powder; it's 'Miracle Grow'."
