Myth No. 1: You can float a check longer if you write in red ink. The theory is that a bank's equipment can't scan red ink, so it takes longer to process the check.
Myth No. 2: You don't have to pay income tax -- it's illegal. Only foreign income is subject to Uncle Sam's cut, the story runs, and there's a form you can file to exempt yourself. But no one will tell you about it.
Myth No. 3: I'm under 18, so I can't be held accountable for a debt. (Variation: Credit-card debts are wiped out when you turn 19.) Spring-breakers love to use this one to justify running up a cruise or resort-hotel bill on their credit cards.
Myth No. 4: My hotel key card has my credit-card information. The ramification is that you'd better clutch it tightly or a con will decode it and rack up a big bill.
Myth No. 5: Boycotting a few gasoline brands brings gas prices down. Poor Exxon and Mobil. They often show up as the bad guys in a mass e-mail urging Americans to avoid their pumps on a particular day.
Myth No. 6: It's better if you don't sign the back of your credit card. Some well-meaning pigeon decided one day this would protect him from identify theft.
Myth No. 7: You can make a pile of dough by helping a foreigner solve his money problems. "Hello, my name is unpronounceable, and I need to get money out of my country. Will you let me use your bank account?" is the gist of this e-mail plea.
Myth No. 8: You can now opt out of having credit bureaus give your information to anyone who asks. Just call (888) 567-8688 and give them the Social Security numbers of everyone in the household in a single call, says the message. But hurry -- you only have 60 days to take advantage of this ability.
Myth No. 9: You can buy your way out of points on a speeding ticket. If you pay a bit more than your fine actually is, the state will send you a refund check for the difference.
Myth No. 10: Hotel Bibles often have $100 bills tucked into them. Heard the one that Gideons leave $100 bills in their hotel Bibles to reward folks who turn to the Good Book?
