Tight skirt
In a crowded city, at a crowded bus stop, a beautiful young woman was waiting for the bus. She was decked out in a tight leather mini-skirt with matching leather boots and jacket.
As the bus rolled up and it became 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 on the bus. Slightly embarrassed and with a quick smile to the bus driver, she reached behind her and unzipped her skirt a little, thinking that this would give her enough slack to raise her leg.
Again, she tried to make the step onto the bus, only to discover she couldn't! So, a little more embarrassed, she once again reached behind her and unzipped her skirt a little more and for a second time attempted the step. Once again, much to her chagrin, she could not raise her leg because of the tight skirt.
So, with a coy little smile to the driver, she again unzipped the offending skirt to give a little more slack but again, was unable to make the step.
About this time, the big Texan that was behind her in the line picked her up easily from the waist and placed her lightly on the step on the bus. Well, she went ballistic and turned on the would-be hero screeching at him, "How dare you touch my body!! I don't even know who you are!!"
At this, the Texan drawled, "Well, Ma'am, normally I would agree with you, but after you unzipped my fly three times, I kinda' figured that we was friends."
