No way, man, Sesame Street is hella cool. The thing that I love and hate at the same time is that Sesame Street is kitsch-cool now. You can find t-shirts, bags, etc with Sesame Street designs.
It irks me because I was into Sesame Street LONG before kitsch was the thing. My dad bought me a bike when I was in high school (way back in 90-92) with a Big Bird license plate on it. I still have the thing. NOBODY thought it was cool back in the day. Now? Hot Topic fodder. Le sigh. I hate it when corporate America decides my favorite uncool thing is now cool.
