Avery Schrieber on Sesame Street?

[Pug Lover]

I could be wrong,but I seem to recall a Sesame Street segment with Kermit and Avery Schrieber.He told Kermit he was terrified,yet he was laughing himself silly.The only other thing I remember about this skit,was Kermit going"GAGGO GAGGO GAGGO"to the guy and scaring him to death.Out of sheer terror,Avery storms off screen screaming hysterically[and you hear a door slam behind him,not visible to the camera].Correct me if I'm wrong.I might not be thinking of the same guy.It could have been someone else.Not Avery Schreiber.Though I'm well aware of him guest starring on The Muppet Show.[I have that episode taped.]
