AKA: No, There Are No Threesomes In This Episode
As a series continues on, the temptation to do sequel episodes to well known and well liked episodes becomes greater and greater. Coming up with new unique ideas for a show, especially a show with such a high bar for weirdness, gets more and more difficult every season and you never know what will or will not please the fans. But a follow up to an old episode, that's easy to come up with, and if it includes some fan favorite characters who don't usually get a lot of screentime, well you can sure that will keep the fans happy, if nothing else.
