Casey Willis has been working with Adam Reed and Matt Thompson for over 15 years. When not writing songs about interracial buttocks, he can be found hurting feelings with his acerbic notes. His co-workers describe him as "incompetent" and "a classic example of failing upwards." Willis went to Japan once and never lets anyone forget about it. He enjoys working voiceover sessions with Archer's wonderfully talented cast and then talking junk about them behind their backs.
