Desperate Single Female (a Bit NSFW)

A desperate single woman is trying to get married. She places ads that read: "Single female looking for well endowed male for marriage purposes. Social status and physical appearance not critical." The next day, the front doorbell rings. She opens to find a quadriplegic (no offense) handsome man on an power wheelchair. - How may I help you? - I'm here concerning the ad. - Well I don't mind your physical condition, but I have doubts about my only requirement, you know... - Oh yeah? and how do you think I was able to ring your doorbell???
