There's an old sea story about a ship's Captain

Who inspected his sailors, and afterwards told the first mate that his men smelled bad...

The Captain suggested perhaps it would help if the sailors would change underwear

The first mate responded, "Aye, aye sir, I'll see to it immediately!"

The first mate went straight to the  sailors berth deck and announced,

"The Captain thinks you guys smell bad and wants you 
to change your underwear."

He continued,
"Pittman, you change with Jones, 
McCarthy, you change with Witkowski,and Brown, you change with Schultz."
