I could not agree with you more. Elmo’s such a delight in interviews, since his conversations are really off the cusp and not necessarily scripted beforehand. I think it shows a great deal of Kevin’s sense of humor. He manages to keep Elmo kid friendly, but sneaks in some humor for older audiences as well.
My favorite one is still the Cinema Arts Center panel-style interview, where it’s Dave/Gonzo, Kevin/Elmo, and Fran/Zoe. Lots of amazing, hysterical banter, and if you haven’t watched it yet I strongly recommend that you do.
