Sit a kid in front of a TV for an hour a day and a parent is bound to find something that offends them, other than the fact that plopping impressionable minds in front of a TV unsupervised is considered "good parenting."

Sesame Street is no stranger to controversy. Critics, cynics and crybabies have called out the show on everything from questionable behavior to the ambiguous situations...of puppets. Of course, all of these complaints and cackling criticisms just scratch the surface of a much bigger issue that has largely gone unaddressed: the total loss of our sanity and grasp on reality.

So as we look back at the last 40 years of television's greatest children's show, we see some speed bumps along the way. These are the ones that caused the greatest loss of tire pressure.
