I would say pretty much the same things as far as the street segment, which is about all I saw. But, I will say this - the continuity was great, but this would have been the perfect place for a throwaway line with Gina saying, "Well, Elmo, I'm still his Mommy, so while Gordon's wife Susan babysits him, I still like to spend lots of time with him, too."
There was a clip from the late '80s or early '90s? That's awesome.
It was a bit dull; it would have been better if Elmo asked something like, "Why can't someone else watch him?" (Thus explaining Susan's absence.)
The word not only seemed tacked on, but simplistic for a "word of the day." However, I may be biased here; I was reading "Peanuts" books at 3-4, and with Charlie Brown and the others, it was very easy to pick up on what a sigh is. Maybe that is a more advanced word than I think.
I thought the "word on the street" would be "jealous" with another dimention being mentioned; that sometimes it's not just a sad feeling, sometimes a jealous person gets very angry at the person receiving special treatment. I can see why they didn't have Elmo mad at Marco, but it deserved to be brought up, and that would have been the time. (It doesn't have to be raging jealousy - just like the one "FUll House" episode where Michelle, 3, wants the baby the guys are watching to go home.)
That anger might not come about if the person talks about their sad feelings right away. But, that would have been something the celbrity could have said if that was the word - that "sometimes if you dont' talk about and get through those feelings, jealousy can make you very angry."
