Craig D. Smith points out another lapse of logic in that Dick Van Dyke Show reunion special. Ritchie Petrie moved back to New Rochelle, bought his old childhood home back from the folks his parents had sold it to, moved in…and not only decorated the living room exactly as it was in the sixties but somehow GOT THE SAME PHONE NUMBER THEY USED TO HAVE. At the beginning, when Alan Brady calls for Rob, Ritchie answers in that house. How did he manage that?
