Joke of the week

I am proud to be able to present my joke of the week for the twentieth time. Enjoy it and have a nice Sunday! Griff
At a crowded city bus stop, a beautiful young woman wearing a tight leather skirt was waiting for a bus. As the bus stopped and it was her turn to get on, she became aware that her skirt was too tight to allow her leg to come up to the height of the first step of the bus. Embarrassed, she reached behind her to unzip her skirt a little, thinking that this would give her enough slack to raise her leg. She tried again to take the step, only to discover that she couldn’t. Once again she reached behind her to unzip her skirt more, and again she could not make the step.
A large guy who was standing behind her picked her up by the waist and placed her gently on the step of the bus. She went ballistic and turned on the would-be Samaritan. "How dare you touch me! I don’t even know who you are!"
The guy smiled and drawled, "Ma’am, normally I would agree with you, but after you unzipped my fly several times, I figured we were friends."
