[[Creator/RobPaulsen Gee, Mr. LaMarche, what do you want to do tonight?]]

[[WesternAnimation/PinkyAndTheBrain The same thing we do every night, Paulsen]]...[[TakeOverTheWorld try to take over the world]]!

Yup, he is best known for the voice of The Brain in ''WesternAnimation/PinkyAndTheBrain''. In creating the voice for Brain, [=LaMarche=] says he looked at a picture of the character and immediately thought of Creator/OrsonWelles, although the character wasn't modeled after Welles. Voicing Brain gave [=LaMarche=] the opportunity to make use of his signature impersonation of Welles. Many Pinky and the Brain episodes are nods to Welles' career. [=LaMarche=] won an Annie Award for his role as the Brain.

He also has roles in many commercials, including (since 2009) that of the narrator for Lexus TV ads.
