When was he on Arrested Development?
Third season. Richard Belzer appeared as himself in "Save Our Bluths," and then Munch appeared in either the next episode or the one after that.
Tobias had been arrested, and the police had come up with an idea for a sting operation on the Bluths. They put Tobias in a program where criminals made collages; the idea was that by making a collage, he would subconsciously reveal secret details of what the Bluths were up to. The person in charge of this sting operation? John Munch.
