A woman visits her husband in prison. They have a long talk, and then the guard tells them their time is over.
The woman gets up to leave, but before she reaches the door, she turns to the correction officer:
"You shouldn't make my husband work so hard, he's exhausted!"
The officer laughs: "Work? Ma'am, all he does is eat, sleep, and sit in his cell. He doesn't even go outside in the yard!"
"Don't you lie to me!" Said the wife hotly, "He just told me he's been digging a tunnel every day for months!"
