How to evade the law. Almost.
Three Rahs, Tom, Dick and Harry, abscond from their college dorm. They run for miles through the countryside until they came upon an old barn where they decide to hide in the hayloft and rest. When they climb up, they find three large potato sacks and decided to climb into them to hide.
A couple of hours later the search party comes into the barn. The chief tells an officer to go up and check the hayloft. The officer climbs up and shouts, "Just three potato sacks up here chief."
"What's in them?" shouts the chief, so the officer kicks the first potato sack. Inside, Tom is hiding and he goes "Woof! Woof!" The officer tells the chief there's a dog in one sack.
Then he kicks the next potato sack. Inside, Dick is hiding and he goes "Meow!" The officer tells the chief there's a cat in the next sack.
Then he kicks the third potato sack. Inside, Harry is hiding and he stays silent. So the officer kicks it again, harder, and Harry shouts "Potatoes!"
