Carl Carlson

Carlton "Carl" Carlson, Jr. (voiced by Hank Azaria) is a recurring character in The Simpsons. 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.

Carl also attended Springfield A&M University and possesses a master's degree in nuclear physics. Mr. Burns once implied that he was a war hero.
