No, seriously, it makes perfect sense. Let me count the ways:

1) He's purple.

2) He's fictional.

3) He's prehistoric.

4) He's all the time talking about how we should all cooperate and get along with each other.

5) He has the same name as both a Democratic congressman and a Republican president's dog.

6) He annoys the living hell out of me.

Look, I'm all in favor of teaching the little kids to cooperate and get along with each other, and Barney provides a valuable service for that demographic.

But if the little kids are plotting to conk teacher with a lead pipe and take her money, or the nerds are facilitating their own beatings, then "cooperation" somehow doesn't seem quite so benign anymore.
