A young actor named Charley Koontz was the best thing about last night’s Community episode, managing to steal his scenes by not trying to steal them — a low-key, human performance that instantly made this new character the most likable guy in that room. Then Community ended and the flailing Perfect Couples began, and who was a guest on that show? Charley Koontz. That’s one guy, playing two different guest parts on two different shows that air one after the other on the same network. It probably wasn’t planned this way, since Perfect Couples shot this episode before they knew they’d be airing after Community, but that’s the way it worked out.
We’ve seen people cross over to shows in the same lineup playing the same character, or a star from one show play a guest on another show that night. But playing two different guest roles on the same network in one night is probably rarer. It must have happened before, maybe not one show right after the other, but at the very least in the same block on the same network. A busy character actor might have appeared on, say, two “Must-See TV shows from the NBC glory days. But are there any other examples you recall,where you saw an actor turn up one one show, and then in a different part on the show that followed it?
