Check my credit card signature?

Every time you make a credit card purchase, they’re supposed to match your signature against the one on the back of your card. Nobody seems to check anymore, so I tried to see how far I could push it with wacky signatures like “Mariah Carey” and “Zeus,” which you can read in the original Credit Card Prank.
“The Credit Card Prank” took on a life of its own, vaulting ZUG into the national consciousness. Since then, some thirty million people have read that article — some of them, it turns out, from the credit card companies themselves. Surely, then, they must have learned their lesson. Right?
