Yeah, but then again, with Urkel, the only other interresting character in the series was Carl. Other than that, the mystery of what happened to the little girl who's greedy mother priced the child actor right off the show is the only thing that gets me interrested in watching it again. Not that I didn't like it when I was a kid....
Elmo on the other hand is part of a very diverse and interresting cast. Take away characters that have been retired, or just don't have a suitible recast, you still have Bert, Ernie, Grover, Cookie, Bird, Snuffy, Oscar, the list goes on and on. Now I give credit to the merchandise. They have started to focus more on Ernie, Bird, Cookie, Abby, and Oscar. But still, the balance is still skewed. Until you get to the stuff driven to collectors and older fans. Elmo does have adult sized mens T's, but its more common to see Bert and Ernie, or the Ensamble cast. or Oscar. (Still kinda depressed they never made an adult Telly Shirt)....
which actually brings me to the next item. How the shell is Telly still underrepresented in merchandising? Elmo may be in every episode, but Telly's in most of, if not every other episode. But other than a mention in Family Guy, you never hear much about him. Even Baby Bear gets a little representation from time to time.
