A girls puts an ad online requesting a man who won't hit her or leave her and is a great lover.

A few days later her doorbell rings and she finds a man with no arms and no legs.

He says to her, "I have no arms, so I can't hit you, and I have no legs, so I can't run."

She responds, "But the last part..."

He grins and says, "How do you think I rang the doorbell?"
