He was written out of the show when Larry Romano, the actor who plays the part of Richie, asked to be let out of his contract so he could leave the series as he was offered a role in another sitcom, the NBC-TV series Kristin, which was intended to be a star vehicle for actress Kristin Chenowith, which, unfortunately, for he and the others associated with that show, would only last for six episodes before being cancelled. His final appearance is in "Paint Misbehavin'", his only appearance in Season 3. He could also be briefly seen in the ending montage in the series finale episode, "China Syndrome (Part 2)".
