A woman got married, but her husband was abusive.
She got remarried and that husband ran out on her.
She got married again and that husband failed in bed.
Finally, she put an ad in the paper: "Looking for a man who won't abuse me, won't leave me, and won't fail me in bed."
The next day, the doorbell rings. There is a man with no arms and no legs.
"Hello, I saw your ad in the paper," he says.
"Tell me a little about you."
"Well, I have no arms, so I can't hit you. I have no legs, so I can't run out on you," he replies.
"How do I know you're good in bed?" she asks.
He says, "I rang the doorbell, didn't I?"
