Mr. Snuffleupagus was my favorite character on Sesame Street. When I was a kid my parents bought me the whole series on VHS (up to that point) so I watched it all the way through. Because of this I saw the saga of Snuffleupagus play itself out.
I love to tell people about my theory of Sesame Street (actually I stole it from Slacker but whatevs) which is that the characters are all the sorts of miscreants one might encounter on the streets of a city: Oscar is a junkie; Cookie Monster’s a crackhead; Elmo is a speed freak; Bert and Ernie are gay; etc. But when I get to the part about how Big Bird is on acid and that one of the proofs was his imaginary friend Snuffleupagus, people are like what?
What these people forget or don’t know, is that for years Big Bird was the only one who saw Snuffleupagus. He would have conversations with Snuffy, sometimes musing with existentialism, but by the time Big Bird could get adults to come and see for themselves, this amazing creature had vanished into thin air.
