The Komedy Krab was a stage show seen only in the episode Squirrel Jokes.
Mr. Krabs came up with the idea of a stage show to bring in customers (or an audience). It started somewhere around 2001. During the three nights that the stage was active, SpongeBob introduced new jokes based on squirrels, giving him much praise. However things started getting out of hand, as Sandy was constantly treated as a person with low intellect. SpongeBob realizes his damage and made new jokes that made fun of all sea creatures from sponge to crabs to fish.
