This one was used on me LAST NIGHT:
Here's the scenario--I was at my grandmother's condo, and I was walking out the door, and these two guys walk by and one says, "Good evening"...and me being the nice person I am, replied back. The guy continues to try to make small talk, and then cuts to the chase, and asks me if I have a man, and I was like, "Yeah..." This dude then whips out his business card and says to me that I need to have a spare. I then proceed to have this blank look on my face, and get this, this man said to me, "Well, you got a spare tire for your car in case your tire goes flat, right? Well then in case your man doesn't act right, I can be your spare man!"

that was a new one for me.
