Without a doubt, plenty of students at Texas A&M have heard the urban legend that putting a penny under your tongue will help you pass a Breathalyzer after you've pulled over on suspicion of DUI.

But sadly, the story is nothing more than just that -- an urban legend. Although the origins of this story are unclear, the idea seems to be that the copper in a penny will cause a chemical reaction with human saliva that will trick a breathalyzer and thus help a driver avoid a DUI. However, there is no scientific basis for this belief

Proof of this comes to us from Athens, Georgia, home of the University of Georgia. There, a 25-year-old man was pulled over around 4:45 a.m. after a police officer observed him driving erratically.

The man claimed that he had not been drinking, but he then blew a 0.17 at the scene, which is more than double the legal limit of 0.08.

At the station, however, police tried once again to test the man's alcohol level, but they noticed that he was only pretending to blow into machines and that he had something in his mouth. The eventually determined that the man had a penny under his tongue because he was trying to trick the Breathalyzer.

Of course, it did not work and the man has now been charged with DUI and with improper driving. While this man cannot be faulted for trying to evade the harsh penalties associated with a DUI, a better idea would have been to work closely with an attorney to make sure his rights are observed.
