Twice. Pulled over on one of the occasions. I acted as sober as possible. He still made me get out walk the line, count to 30, stand on one foot, etc etc. Passed all those somehow. I was pulling into the parking lot for my dorm so he let me go without a breathalyzer. He even knew I probably wouldn't have passed that, I knew I definitely wouldn't have passed it. Definitely one of the more scarier moments for my life, DUIs can hurt you pretty good.
