I saw this once on Sesame Street in the 90s. It's one of the funniest things ever. I love Cookie and Grover and seeing them do an adaption... sort of... is just the best. As well as the clever little in jokes for the older viewers, I love those as well. I mean, Alistaire Cookie? That alone is worth it, and it actually just gets better as it goes along.
It's the end that cracks me up every time I watch it. It was so unexpected the first time I saw I wanted to see it again. Thanks to youtube I can, and it's STILL just as funny. I won't ruin it, just watch.
