the lonely woman

A lonely woman, decided that it was time to get married. She put an ad in the local paper that read:
HUSBAND WANTED! MUST NOT BEAT ME, MUST NOT RUN AROUND ON ME, AND MUST STILL BE GOOD IN BED! ALL APPLICANTS PLEASE APPLY IN PERSON. ... 3 weeks went by without a reply, and then the doorbell rang. Much to her dismay, she opened the door to see a gray- haired gentleman with no arms or legs sitting in a wheelchair.
The old woman said, "You're not really asking me to consider you, are you? Just look at you ... you have no legs!" The old man smiled, "Therefore I cannot run around on you!"
She snorted. "You don't have any hands either!"
Again the old man smiled, "Nor can I beat you!"
She raised an eyebrow and gazed intently. "and what makes you think you satisfy me in bed?" With that, the old gentleman leaned back, beamed a big broad smile and said, "I rang the doorbell, didn't I?"
