carl carlson

Carlton Carlisle "Carl" Carlson, Jr. is a recurring character in The Simpsons and a supporting character in The Simpsons Movie. He is a safety operations supervisor from Sector 7G of the Springfield Nuclear Power Plant, where he works alongside his childhood friends Lenny Leonard and Homer Simpson.

Carl is a self-restrained organized (although not maniac about it, like Frank Grimes) employee and likes to call himself "an urban Lenny". It is hinted in the series that he and Lenny may be more than just friends.
