The Credit Card Prank

This smart ass tries his best to muck up his credit card signature to see if he can get away with it.

Years ago I worked at a hospital installing small TVs for patients and I carried one of those old school credit card swipers that made an impression of the card. Some of the patients I would hook up a TV for where unable to sign their own name, so I would often do it for them and the credit card company never noticed.
