Muppet Labs

Muppet Labs premiered in the episode with Paul Williams and lasted all five seasons of The Muppet Show. During the first year, the sketch only featured Dr. Bunsen Honeydew. Beginning in season two, Bunsen's assistant, Beaker, was added.

For the first two seasons, the set consisted of a plain colored background (usually blue or white) with some cabinets made to look like computers and a desk. In the third season, the set was changed to look more like an office, with a wall clock (which was square in the third season, and circular after that) and a city backdrop.
