I have a question about "Everybody Loves Raymond" that's really bugging me. Has Amy got a brother called Russell? In one episode, Ray goes into his comic shop and I'm sure his name was Russell.

Amy MacDougall Barone doesn't have a brother named Russell. His name is Peter.

Peter was originally introduced as "Russell", the owner of a comic book shop, and was played by comedian Paul Reubens in a one-time appearance. After his cameo appearance, however, Reubens was arrested on child pornography charges, and Ray Romano objected to Reubens being part of the show's cast Russell abruptly became Peter because in Season 7, Episode 14: "Just a Formality", Peter (Chris Elliott) mentions meeting Ray at the comic book store (which was Russell).
