The name of the talking German fish on the hit TV comedy American Dad!.
He was originally a German man, but was eventually turned into a fish by the CIA then Stan took him in. He now lives with Stan and the rest of his family. Despite his delightful personality (filled with multiple funny German words to ease the audience during moments on tension in the show), Klaus is basically universally hated and is often told to shut up despite his keen knowledge, good ideas, and helpful advice.
He is also in love with Francine, Stan's wife, and he is orange.
Klaus: (attempts to give good advice to whomever during an episode)
Francine, Roger, Steve, Stan, Hayley, or any other person in the cast of American Dad!: "Shut up, Klaus."
