A man was sent to prison for 20 years. While inside, he found an ant and taught it tricks: how to beg, play dead, roll over and jump.
When the man was finally released, he took the ant in a matchbox and headed for a bar.
Sitting at the bar, he took out the matchbox, emptied out the ant, and said to the guy beside him: “You are not going to believe what this ant can do.”
He took the ant through all of his tricks, and the guy was impressed. "You could make a fortune with that!" the guy said.
Excited, the ant's trainer called over the bartender. "You see that ant?" he barked.
The bartender put his finger on the ant, twisted it, and said, “Sorry, sir, it won't happen again.”
