Because this is a cotillion episode -- one that everyone in town seems to be attending with a curiosity and casual nostalgia equivalent to if you wandered into a dance at your old high-school. except that here, nobody pauses to wonder who the creepy old person by the punch bowl is -- we get some flashbacks to the original, which take us down a very special follicular memory lane. Chuck was a Beatle, and Nate was what Justin Bieber THOUGHT he looked like two years ago.
