3. Incest Is The Best
Episode: "Wedding Videography" (Season 6, Episode 12)
The show's penultimate episode to date revolves around the totally unforgettable, disastrous wedding of Garrett (Erik Charles Nielsen), who learns that he's about to marry his cousin, and after some encouragement from the study group, he goes ahead with it anyway.
The tag then cuts to the episode's credited writer, Briggs Hatton (played by Matt Gourley), who addresses the episode's theme of incest, explaining that during his time spent researching incest, he discovered that state laws regarding it are woefully out of date.
Basically, it compounds the episode's general attempt to dispel some of the more lurid myths surrounding first-cousin incest in particular, yet does so in a delightfully weird, totally unexpected, and wildly hilarious way.
