Whoops: Not everyone realized 'WTF' was slang for a certain vulgar phrase.
RALEIGH, N.C. — Thanks to some text message-savvy grandchildren, North Carolina drivers whose license plates have the potentially offensive "WTF" letter combination can replace the tags for free.
The News & Observer of Raleigh reported Tuesday the state Division of Motor Vehicles has notified nearly 10,000 holders of license plates with the letter combination. Officials learned last year the common acronym stands for a vulgar phrase in e-mail and cell phone text messages.
But this week, the DMV officials got another surprise when they learned the same letters appeared on the agency's own Web site on a sample personalized plate.
"I can't believe it," DMV Commissioner Bill Gore said Monday when told about the online glitch. "Obviously, I didn't know it was there."
Officials are working to remove the sample plate.
The "WTF-5505" used on the Web site's sample plate was the first random letter combination available when DMV switched from blue- to red-lettered plates, officials said. DMV spokeswoman Marge Howell received a sample plate WTF-5506 to use as a prop for news stories about the switch.
A 60-year-old technology teacher from Fayetteville complained about the plate last July after her teenage grandchildren clued her in.

While it's preferable to keep a consistent routine and sleep schedule, it's not always possible. Experts now say that if you're a little more stressed out or anxious or just not tired, you're better off staying up than hitting the sack. Our bodies are the best gauge of when we need some shut-eye. Insomniacs often trap themselves into a cycle of anxiety wherein they can't get to sleep for fear of not being able to fall asleep. Instead of forcing yourself into bed at an arbitrary time when you're not tired, spend a little time doing a relaxing activity—reading, listening to music, meditating, taking a hot bath—and then go to bed when you feel like you're ready to lie down and close your eyes. Studies have shown that you're as likely to fall asleep then as when you force yourself to adhere to a self-imposed bedtime—you'll just enjoy the process of relaxing more and will sleep better. 
A Brazilian study showed that while heavy aerobic exercises and anaerobic/strength training exercises had little to poor effect on sleep patterns, light to moderate aerobic exercise, like a relaxing walk or a medium aerobic workout, actually helped people sleep better. The old saw about jumping around to "get the blood moving" actually proves to work the opposite way. People who engaged in a bit of light exercise before bed fell asleep more quickly and stayed asleep longer than the more sedentary members of the test group. A UCLA study also found that in older adults (59 to 86 years old), a regular tai chi regimen (regardless of when it was practiced) seemed to provide better sleep schedules and fewer sleep disturbances compared to doing nothing. 
A study from the Tufts New England Medical Centre in Boston found that in the four companies (airline, manufacturer, pharmaceutical company, and law firm) with a little over 4,000 total employees, the loss of productivity due to sleep issues added up to about $54 million. Much of these costs were attributed to prescriptions for sleep aids, sleep-related disorders like depression, and safety-related costs due to people falling asleep on the job. The rest had to do with general productivity loss. The study estimated the cost of insomnia as 2-1/2 weeks of productivity annually for every worker.
