John

From Muppet Wiki

John is the name of an unseen (and unheard) cameraman for Sesame Street News. He often is sent on location with Reporter Kermit to film a newsflash. Kermit is often caught off-guard talking with John and other crew members prior to his newsflash going "live". Kermit addresses John by name telling him to get a close-up of the Invisible Man's tap-dancing feet.
