Stealing chickens

Every night, for a few days now, Bobby and Rudy have been stealing chickens. The owner noticed that his chickens were missing, so he decided to wait for the thieves. In the evening, he took a spade handle and hid in the chicken coop.

After a while, Bobby and Rudy arrive.

"Rudy, you keep watch, and I'll get the chickens," says Bobby.

Bobby goes into the chicken coop, but the owner hits him across the teeth with the spade handle. Shocked by the pain, Bobby comes out with his hand over his mouth.

"Bobby, where are the chickens?", Rudy asks him.

Bobby mutters: "You go in, I can't stop laughing!"
