Hazards of tight dresses

In a crowded city at a busy bus stop, a woman who was
waiting for a bus was wearing a tight leather skirt. 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.
Slightly embarrassed and with a quick smile to the bus driver,
she reached behind her to unzip her skirt a little, thinking that
this would give her enough slack to raise her leg.
Again, she tried to make the step only to discover she still couldn't.
So, a little more embarrassed, she once again reached behind
her to unzip her skirt a little more. For the second time,
she attempted the step, and, once again, much to her chagrin, she
could not raise her leg. With a little smile to the driver, she
again reached behind to unzip a little more and again was unable to
make the step. About this time, a large Texan who was standing behind her
picked her up easily by the waist and placed her gently on the
step of the bus. She went ballistic and turned to the would-be Samaritan and
screeched, "How dare you touch my body! I don't even know who you are!"
The Texan smiled and drawled, "Well, ma'am, normally I would
agree with you, but after you unzipped my fly three times, I kinda
figured we was friends."
