Here's the joke

This guy was serving a life sentence in solitary and he was about to go out of his mind, so one day he saw this little ant crawling across the floor. He thought I got the rest of my life, so I could train this little ant, at the same time give me something to do and relieve the stress.

So he started teaching the little ant. Many years went by and with the help of courses and lessons he had got in the mail he taught the little ant all about law. The little ant got so good at his new trade that he got the man freed. When the papers heard his story they went wild. When he left the prison a bunch of scientist met him at the gate.

He carried the little ant in a match box in his shirt pocket. He showed him to the scientist.

They offered him thousands of dollars for the little ant, to use in their research. But he refused them saying “this little ant and I have been together for so long I could not part with him, it was he that got me out of prison"

So they started on their way. "What would you like to do?" asked the man. “I would like to go to a bar like you told me so much about" answered the little ant. So off they went to find a bar. In the bar the man started drinking and would give the little ant a drop from time to time.

So feeling good he started pestering the bartender.

"Do you know who I am?" he asked the bartender, “No, I don't" said the bartender"

"I'm the man the papers have been writing so much about."

"Still don't know you" said the bartender and off he went.

So he took the little ant out of the box and sat him on the bar.

Calling the bartender over he said "You see that little ant there on the bar?”

“I sure do," and with his thumb the bartender squashed the little and said "How the hell he got in here, I just exterminated the place yesterday!
