Grover psychosis

So the little man doesn't get much tv. There are multiple reasons for this and they aren't all part of our Concentrated Rule-based Approach to Parenting (CRAP). I just don't watch much tv, especially not during his waking hours. And we also don't think a 10-month-old needs to be pacified like that too much. He'll have plenty of time for tv later.

But today I flipped it on and there was Regis and somebody talking to Tom Hanks. So I flipped around, stumbling upon Sesame Street. Grover was there talking to an Alaskan sled dog (Akita? Huskie?). Anyway, the boy immediately started jumping for joy. No, literally, jumping up and down smiling and giggling. They then cut to a little film about native Alaskans. His enthusiasm dipped a bit, but I think he was still eager for Grover to come back.

What is it about Muppets? I mean, the boy wasn't just happy, he was nearly convulsing with elation. He definitely didn't have the same reaction to Regis.
