Toilet Earnings

Obviously we all get email jokes sent to us, and most of them are pretty lame. But there is one that I remember, and whilst I suppose not technically a joke, it did make me laugh. It was an excel spreadsheet, onto which you entered how much you were paid annually. Then there was a button that said Start, and another that said Stop and what you did was, you started the clock when you went on a toilet break, and then when you returned you stopped the clock and the spreadsheet would calculate how much money you made whilst going to the bathroom.
