Kevin in Everybody Loves Raymond
Before Kevin James started in King of Queens he was in Everybody Loves Raymond playing his namesake as one of Ray's friends. Later on when he made appearances in ELR he was playing Doug as a crossover from King of Queens. "Keivn" from ELR faded away.
Was "Kevin's" last name or occupation ever established in ELR? If not its fun to think about how the Kevin in the new series "Kevin Can Wait" is one of the same as Kevin in the early seasons of ELR.
