A 22-year-old woman on probation for a drunk driving conviction thought she had fooled investigators when she passed a breathalyzer test after a night of drinking. She probably would have gotten away with it, too, if she hadn't bragged about it on Facebook.

Colleen Cudney took the random breathalyzer on the day after St. Patrick's Day. After miraculously passing, she wrote, "Buzz killer for me, I had to breatalyze this morning and I drank yesterday but I passed thank god lol my dumbass."

Her dumbass, indeed. Westland, Mich. police saw the post and passed it on to the probation office. When they called Cudney to schedule a urine test, she hung up on them, violating the conditions of her probation for a 2012 DUI.

Cudney would have been off probation in a few weeks, but now she faces up to 93 days in jail. She's due in court Tuesday.
