Something I've noticed about Elmo.

[Muppet Frog]

Did you ever notice that Elmo interacted with every cast member and Muppet of SS except for Simon Soundman, Don Music, Harvey Kneeslapper or Little Chrissy and the Alphabets?

I doubt Elmo interracted with Professor Hastings, The Busby Twins, Sam the Robot, Lefty, or Leslie Mostly.

I know Elmo interacted with Farley on The Computers in Your Neighborhood.

And how could Elmo not meet the infamous Answer Lady!

Doubt Elmo's ever met Roosevelt Franklin or Beautiful Day Monster either, for that matter. But there's a lot of characters that have come through Sesame Street since before Elmo was around, so it only stands to reason that there will be a number of older characters that he hasn't interacted with. But it is cool for the times when he has interacted with Farley (as in the aforementioned "Computers in Your Neighborhood" song) and other older characters.
