This one had me raging for hours afterwards:
I was at Walmart, one which has BIG WHITE ARROWS painted on the parking lot to tell you which way to go down the aisle because the aisles are too narrow for two cars to pass each other. So I was going the correct way down the aisle when all of a sudden I'm met by a moron in a PT Loser going the wrong way, so I stop, waiting for him to back up, as that is the logical thing to do when you're in the right and their in the wrong. Well not ten seconds go by and this guy lays on the horn, waving his arms, flipping me off, and generally just freaking out over the fact that I'm not moving out of his way! So, trying to remain calm and not start a fight, I backed up into a parking space to let this colossal idiot through. Well he couldn't just take his dumbass by me, nope, he drove up, stopped his car in front of mine and started yelling and cussing at me about how I have no respect for others and yada-yada-yada. And with that, I turned around, grabbed my tire iron, stepped out of the truck, and nicely convinced him that going on his way would save his car and windshield from considerable damage. Here's the kicker, he had one of those "Respect Life" custom license plates and a Mensa bumper sticker!! Obviously Mensa must have switched from taking people with high IQs to taking people who can't comprehend basic shapes....
