Gym Membership :lol:
I remember a story my teacher once told me about punch cards (he went to university when they were all you used to program lol), one of his friends had a huge box of punch cards for his coursework, a completed program. He also had a large chunk of fruit cake. My teacher muddled up the cards a little and of course when the friend ran them through the machine it came up with a Programming Error. A note then appeared saying that the program would be restored in exchange for the fruit cake!!
Said fruit cake was exchanged and all my teacher did was to put the card at the back of the box at the front - all he had done was move the first card to the back :lol:
