Did you ever notice with a show you watch frequently in reruns that there are one or two “phantom” episodes? Even though you’re a loyal viewer, you ALWAYS miss the episode when it airs in sequence. And something about it seems a bit off. I just saw one of those episodes, and the only reason I caught it at all is because my PVR is recording all Seinfelds. It was the one where Frank puts a pool table in George’s old room, and Jerry is on the Charles Grodin show. Another example would be the Brad Goodman episode of the Simpsons.
