Yay! My dream is coming true! I love Sesame just a *tad* more than the Muppets (although I dearly love the Muppets), so this is extra special!
I echo all of the suggestions everyone made, but have a special request - could you please do a Harvey Kneeslapper with a number one or something else from his antics? Example: "Harvey: Do you want one? Ernie: Sure! Harvey: <Slaps number one on Ernie's chest> There you go!" I think that would be rich!
Also, how about Simon Soundman? Love that guy!!!
This is probably a long shot, but I'd love to see figures of the non-muppets, too, like Linda, Bob, Susan, Gordon, Mr. Hooper and all of the classic cast members.
Lastly, could you leave Elmo out of the line? Just kidding, but I really feel Elmo was the downfall of Sesame Street, unfortunately.
