True story in the news.  Some man got a DUI because his body somehow produces alcohol within him.  He had some kind of yeast in his system, which fermented and caused him to experience what drinkers experience, without ingesting any alcohol, and he wasn't lying when he told the officers that he hadn't been drinking.

Besides that, no one should be driving drunk or even buzzed.  And the guy in the news story shouldn't drive if his body has that condition! Just don't do it.  Please!
