A man is showering up in a locker room with his buddy when he notices
his friend is very well endowed.
"Damn Bob, you're hung!" Jim exclaims.
"I wasn't always this impressive, I had to work for it."
"What do you mean?" Jim asked.
"Well, everyday for the past two years I've spent an hour each night
rubbing it with butter. I know it sounds crazy but it
actually made it grow 4 inches! You should try it."
Jim agrees and the two say good bye.
A few months later the two are in the same locker room and Bob asks Jim
how his situation was.
Jim replied, " I did what you said, Bob, but I've actually gotten
smaller! I lost two inches already!"
"Did you do everything I told you? An hour each day with butter?"
"Well, I was out of butter, so I've been using Crisco."
"Crisco?!?" Bob exclaimed,
"Dammit Jim, Crisco's shortening!!!..."
