World's least funny joke?

Here it goes:

One night at a bar, a man sits down next to an attractive women and orders a drink.

The woman, already on her third or fourth cocktail, turns around, looks at the man straight

in the eye and says, "Listen here: I screw anybody, anytime, anywhere, your place, my place, in the car, on the car, front door, back door, on the ground, standing up,

sitting down, naked or dressed; it doesn't matter to me. I just love to do it all the time"

Eyes now wide open with interest, the man responds, "Hey! I'm in banking too!

It's cute, but why is it not funny? Because bankers don't get it and everyone else knows it to be true.
