So a blonde, a black haired person, and a red head are running away from the cops and they hide in a farm. The black haired person goes behind the cow, the red head behind the pig and the blonde in the potato sack. So when the cop comes and passes the cow the black haired person, says mooo. So the cop goes away. When the cop passes the pig the red head says Oink. So the cop goes away. But when the cop passes the potato sack the blonde says, "POTATO!"
