Dusty underwear

One morning, Jeff took a pair of underwear out of the drawer. 'What the ? ? ?' he said to himself as a little 'dust' cloud appeared when he shook them out.

'Joyce,' he hollered into the bathroom, 'why did you put talcum powder in my underwear?'

She shot back: 'It's not talcum powder.'

It's 'Miracle Grow'.'

Thanks Gene
