Pros: Terrific imagination and an eagerness to try new things. Wanna talk about an "Amazing Race" partner who will get you recognized and instantly adored in every nation in the world? Nobody would need to ask for directions or for help with Elmo around. Kids would come out of the woodwork in droves.
Cons: Elmo has a weirdly co-dependent relationship with a large, middle-aged man named Kevin and it's hard to imagine him going any place without him. Producers would have to give their blessing for this unusual trio. Inability to speak in complete sentences might get annoying after a while. Not Grover.
