Skittles Sour commercial where the guy is getting milked. It's disguisting, and tilts me when I watch it.

The cell phone commercials where the parent and the kids argue with eachother, but say the opposite of what they would "normally" say to each other. [censored] off Verizon/cingular/t-mobile. Not all kids talk to their parents like [censored], cause if they did they'd get smacked up side the head.
The commercial where everyone starts yawning. If I had more than one TV in my house I'd throw my shoe through the screen every god damn time it comes on.
Any anti-smoking/anti-drug commercial. It doesn't work [censored]. Now they all suck, go back to the 80's when they were at least entertaining.
