OK, this reminds me of a prank we (okay, I) pulled a few years ago at the Hall........some friends bought this gadget in Florida where one is a box and the other has five different recordings of farts on it. They're really realistic and you can have a field day with it. Anyway, I borrowed it and took it to the hall one night. There was this pathetic sister who always pretended to be sick or dying or some such shit and she sat it this big chair at the back of the Hall. I put the box under her chair and waited for her to answer a question on the KM. Just as the microphone got near, I hit the button. It wasn't loud enough for everyone to hear, but the people around her started laughing and laughing and laughing. She didn't know what the hell was going on and wasn't smart enough to look under her chair.
