Yeah, I was hoping for that one. In my mind, the set should have either had celebrity versions of both Put Down the Duckie and Monster in the Mirror, or it should have just had the original celebrity-free edits of both (the celebrity version of Put Down the Duckei was released on two previous videos, but not the version without celebrities, except mayeb on a Shalom Sesame release). I'm convicned that Sesame Workshop couldn't clear up the appearance of the Simpsons or maybe some other celebrity/celebrities. But I don't know for sure.Though, since it's been forever since I've seen the celebrity version of "Monster in the Mirror," I kinda wanted that version, instead.
But you can watch the celebrity version at both sesamestreet.org and hulu. sesamestreet.org doesn't have any title differences between the celebrity and non-celebrity versions, but I think the description for the celebrity one does mention celebrities (and if in doubt you can make a search for one of the featured celebrities and it'll show up). At Hulu the main image used shows several celebrities (I can't remember whetehr it's listed under "Muppets" or "celebrities").
