A man goes to prison and the first night while he's laying in bed contemplating his situation, he hears someone yell out, "44!" Followed by laughter from the other prisoners.
He thought that was pretty odd, then he heard someone else yell out, "72!" Followed by even more laughter.
"What's going on?" he asked his cellmate.
"Well, we've all heard every joke so many times, we've given them each a number to make it easier."
"Oh," he says, "can I try?"
"Sure, go ahead."
So, he yells out "102!" and the place is dead quiet save for a few groans. Confused, he looks at his cellmate who is just shaking his head.
"Hey, what happened?"
"Well, some people can tell a joke, some people can't."
