A weedy, white-collar criminal gets sent to jail.

While he's being processed, he hears that the guy he's being put with is
notorious for raping his cellmates. "Oh my God!" he thinks, shaking.

When he gets to his cell and meets this guy it's even worse: he's HUGE.
Big muscles, shaved head, tattoes, the whole deal. The white-collar
criminal is near crapping himself.

At lights out, the new guy takes the top bunk and lies there scared to
death. After a few minutes he hears a gruff voice from the bunk below:

"Do you want to play a game?"

"Well, er, what game?"

"There's two games: doctors and nurses or mommies and daddies."

The weedy guy desperately tries to think which game might be safer.

"Mommies and daddies", he says eventually.

"Do you want to be mommy or daddy?"

Again, the weedy guy desperately tries to think of the right answer.

"Er, I'll be daddy." he says.

"Okay."

"So, how do we play this game?"

And from the bunk below the gruff voice says:

"Ok daddy come down here and suck mommys ****."
