So, a lady puts out an ad for a new lover. Many respond, but only one ignites that flame of desire in her loins. They set a date and time for him to come over, both very eager.
The appointed moment arrives, and her doorbell rings. She peeks out the peephole and sees no one. She opens the door to see a man below her, with no arms or legs.
With some confusion, she asks who he is, and it is the name of her expected date.
She exclaims that he must be joking, what kind of lover could he be?
His response was "I rang the doorbell, didn't I?"
