We loved last night's episode of "Community." It utilized the classic sitcom device of stranding the characters into an enclosed location for the entire show (known as a "bottle show"), allowing the gang to play off each other in a concentrated way that lends itself to both humor and character development.
In this case, the study group was trapped in the room because Annie (Alison Brie) was in search of a lost pen, and prevented anyone from leaving the room until they had found it, other plans notwithstanding -- specifically a date with "Gwynnifer" for Jeff (Joel McHale) and a puppy parade for Troy and Abed (Donald Glover and Danny Pudi).
It was a rare television episode that balanced wit and emotion in equal measure. But also, the characters stripped down to their underwear at one point while looking for the pen, Abed's idea being that it will catch anyone who may be keeping it on their person. Check out the clip below to see the cast in their unmentionables.
