A couple decides to get married, despite the fact that the woman doesn't know how to cook at all. After all, he says, they can live on love. After the honeymoon is over, the man goes back to work. One day, he calls from work and asks if his new wife could make some dinner. Knowing full well that she doesn't cook, she asks if they can make love instead. The man agrees, and soon arrives home to find his wife sliding repeatedly down the bannister.

"What are you doing?" he asks, concerned.

"Oh, silly," she says. "I'm warming up your dinner!"
