One day in line for the automatic teller I overheard:
[Person 1]: Gee, I don't get it..
[Person 2]: What's wrong?
[Person 1]: My card wont work.
[Person 2]: Did anything happen to it?
[Person 1]: I don't think so... It wasn't working very well for a while, so I rubbed the strip on the back with a magnet to recharge it... Now it isn't working at all!
