"A man goes to prison" joke with two opposite punchlines.

My grandpa used to tell this joke, one day I heard someone else tell it with almost an exact opposite punchline. I've never tried to type it out before, so sorry if this sucks, but here's how I first heard it:

---

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 goes *nuts*. People are whooping and laughing in a hysteria. He looks at his cellmate rolling on the ground with tears in his eyes from laughing so hard.

"Wow, good joke huh?"

"Yeah! We ain't never heard that one before!"

And here's the other punchline that threw me for a loop after years of hearing this joke:

---

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."

Thanks for reading! I'm much better at telling this out loud, I promise.
