Pops

Pops is an elderly humanoid Muppet who serves as the stage doorman for the Muppet Theater on The Muppet Show. He was first introduced during the show's fifth season, where he was featured in the cold opening of each episode, in a departure from previous seasons which had featured Scooter talking to the guest stars in their dressing room.

Pops is supposed to greet the guest stars when they first arrive at the theater, but due to his forgetfulness and nearsightedness, he invariably needs to ask them "Who're you?" in his slight country accent.

His most famous role was as the owner of the Happiness Hotel in The Great Muppet Caper.
