Notice he was sleeping in Bert's bed which had been tainted by his evil.

Let he who is not a monster be the first to cast stones.

See, THIS is why Cookie Monster is a letter of the alphabet.

youtube comment: "When I was a kid I had a nightmare about cookie monster being tortured by two people on top of a sunny hill. They were burning him and poking his eyes out. He kept yelling and screaming just like in this skit. I realized after watching this that this is what I based my nightmare off of lol. at the end of my dream cookie monster was floating in space in a bubble, dead, and his eyes were crossed out X X. I think this skit scared the shit out of me when I was a kid."

maybe.

Yeah, sure Bert is visiting his grandmother. He's cheating with Oscar the Grouch, that dirty whore.
