Joke: Feldman's wife wakes up in the middle of night to the sound of her husband pacing around the room.

"Feldman," she says. "What's wrong with you? Come back to bed!"

Feldman replies, "Dora, I can't sleep. Tomorrow I'm supposed to pay Levine the $15,000 I borrowed from him and I don't have it. I'm worried sick."

"You owe Levine money and you're worried?" Dora asks.

"Yeah, I can't sleep," says Feldman.

"Silly man," says Dora. "Come back to bed. Let Levine worry."
