One day, a large group of people were waiting for the bus at a local Greyhound station. At the front of the line was a very attractive woman  dressed in a black business vest, white blouse, leather miniskirt, and  high heels.

As the bus pulled up and opened the door, she went to board it, but found  that her skirt was too tight for her to raise her leg to the required height. Looking around and thinking quickly, she reaches behind her and  unzips the zipper on the back of her skirt a little and then tries again.

Again, she finds that she cannot maneuver the step, so once more she reaches behind her and unzips her skirt a little more. With a smile, she  looks at the bus driver and tries to board again. With disappointment, she  finds that she still can't step that high and so with exasperation and a sigh she unzips her skirt the rest of the way down. To her amazement, her leg still will not reach the bottom step.

Finally, a very large Texan behind her gently grabs her by the waist, lifts  her up, and places her on the bus.  

The woman turns to the Texan furious and says, "Who do you think you are to touch my body in that way? I don't even know you!"

Nonplused, the Texan looks at her and replies, "Well, ma'am, after you  unzipped my fly I thought we were pretty good friends."
