The Trained Ant

Joe was sent to jail for 14 years. Not knowing what to do in prison, he caught an ant and trained it. After 14 years of rigorous training, the ant came out of prison with Joe.

Joe went straight to a restaurant and called the waiter. He wanted to show his "pet" to the waiter, so he took the ant from his pocket and let it on the table. He asked the waiter, pointing at the ant, "What is this?". The waiter promptly reached out and killed the ant and replied, "I am sorry, sir".
