A REALLY skimpy skirt

A young woman in a REALLY skimpy skirt was at the bus stop. When the bus arrived and the doors opened she tried to climb the steps. However, her skirt was too tight and her legs couldn't move. So, she reached behind her and undid her zipper.She tried to step up again, and still couldn't, so she reached behind again and played with the zipper.She tried to climb the steps again...still no luck. So, as she reached behind again, a pair of strong hands picked her up and placed her on the top step."What do you think you're doing?", she asked the guy behind her."Well, I figured the second time you undid my fly we were at least good friends!"
