A woman goes to visit her husband in prison. Before leaving, she pulls a correction officer aside and says:
“You really shouldn’t work my husband so hard… he looks worn out!”
The officer chuckles:
“Ma’am, your husband doesn’t work. He eats, sleeps, and sits in his cell all day.”
The wife frowns and says:
“That’s strange… he told me he’s been digging a tunnel for months!”
