We were on the expressway once and this cop came flying by us doing like 90, weaving in and out of traffic. No lights on at all. He gets off at the exit we're getting off at. As we drive towards McDonalds (our destination) we see him pull in ahead of us. We end up behind him in the drive-through and watch as he casually orders his food, and pulls into the parking spot to eat.

My friend (who enjoys being a giant asshole to cops), pulled in right next to him, and made the window-roll-down motion. When the cop rolled his window down, my friend said he observed him driving very recklessly, and asked what the emergency was. The cop just shook his head and laughed and went back to eating. My friend said "Oh, ok. I'd like your badge number, please." The cop looked right at us, flipped us the bird, and drove off. When he left the lot, he squeeled his tires and made them smoke as he just smiled at us with the smarmy, d-bag "I'm a cop and there's nothing you can do" jackass smile.
