Ketchup

Anson had already dripped ketchup from his hotdog on his shirt and shorts when Wendell issued a warning.

"Be careful, Anson, you're about to drip ketchup out of the back of your bun."

Anson face went through a series of strange expressions ranging from amusement to frustration. He kept looking over his shoulder at the floor and finally blurted out, "There's no ketchup coming out of my bum!"
