Many years ago i was watching a co-worker at work. Her head was down and she was busy. I noticed that her skirt had the zip on the back and that the tab thing was sticking up. I further noticed the little hole in the end of the tag.

A quick survey of other staff produced some thread which i tied through the hole inthe zip and then to the chair. She was really very hard working as she didn't notice and it was a further hour before she moved.

I was actually quite suprised when she stood up... the zip was pulled down and her skirt fell to the floor getting a round of applause... honestly i thought it would pull the zip maybe but that would be about it.

She turned around and just said... "oh I might have known it would be you!" while pulling her skirt back on. She turned around and got on with her work.

My boss walked over. "i want a word with you young man! Next time you pull a stunt like that... warn me... i nearly missed it!.
