John's wife Betty always folded his undershorts very carefully before putting them away.

One day John notices a powdery substance falling from his boxers when he took them out of the drawer.

Assuming Betty was just trying to make them a bit more comfortable, he didn't say anything.

Soon the powder became quite abundant and he asked Betty why she was
putting so much talcum in his shorts.

Her reply: "That's not talcum, that's Miracle-Gro."
