Governmento de Argentina
There is a charge to leave your country -- a $20 exit tax. How can that be legal? Even if it is legal, NOT COOL. You'd think a place with "the largest anarchist contingent of any South American country" would be more anxious to send people on their way.
Snow-covered Car Drivers
Even if you've completely scraped all windows and windshields, you're not done. Take the extra two minutes to clear off the snow on your lights, roof, hood, and trunk BEFORE you hit the highway. You might enjoy pretending to drive a comet, throwing off a trail of frozen matter as you speed down the road, but it's NOT COOL.
Ron Paul Supporters
Giving money to a Libertarian candidate? Why don't you just flush it down the toilet? Speaking of...
Hey, buddy. It's been years now. An ape could have mastered this "skill" buy now. Jesus, an alien with no concept of an anus could figure it out. It is NOT COOL to smear your feces on the toilet seat. When you're crapping in the comfort of your assuredly filthy home, you can stain whatever surface you want. But every male on the 2nd floor has to use that bathroom, and we'd appreciate it if you can get your shit together. Literally.
