Season 6: Episode 132: Raybert
Robert meets a beautiful woman who is a big fan of Ray Barone's sports column. But when the woman mistakes Robert for Raymond, Robert doesn't set her straight. Now, Robert has to involve Ray in a complicated plot to keep the woman from learning Robert's true identity. Ray warns him that this could blow up in his face, but Robert keeps it up so he can get her to like him instead of Ray. As Ray expected, things go wrong when she shows up at Ray's house and she tells Debra, who she thought was dead, that she and Ray are dating.
