One weekend, the husband is in the bathroom shaving when the kid he hired to mow his lawn, a local kid named Bubba, comes in to pee. The husband slyly looks over and is shocked at how immensely endowed Bubba is. He can't help himself, and asks Bubba what his secret is.
“Well,” says Bubba, “every night before I climb into bed with a girl, I whack my penis on the bedpost three times. It works, and it sure impresses the girls!”
The husband was excited at this easy suggestion and decided to try it that very night. So before climbing into bed with his wife, he took out his penis and whacked it three times on the bedpost.
His wife, half-asleep, said, “Bubba? Is that you?”
