Oh boy! It's usually much later into a show's run that it gets desperate enough for an episode like this. Maybe it's just a matter of preference, but I really don't like it when programs take their main characters and give them slightly different roles in an attempt to be fresh. The musical numbers, in my mind, did not help either.
What's next? Peter's evil twin shows up or Cousin Oliver comes over to stay at the lab?
On the other hand it could just be an ill conceived idea by the writers/producers and a little tongue in cheek humor. If you like that sort of thing, then maybe this episode will be for you. For me, it was a waste of an hour.
Best of all, it doesn't have much to do with the overall story arc, so you can miss this and not miss a beat at the (hopefully much better) future episodes.
