Season 2, Episode 3 of “Community” is called Abed’s Story. He doesn’t seem to be featured at all, but if you rewatch the story he actually is helping a woman give birth throughout the entire episode.
This was referenced to, by Abed, in the episode where Shirley was giving birth and Abed stepped up to help. It also airs 9 months after the “STD Fair” episode.
I didn’t notice it the first time I watched.
The first time I saw this episode, I didn’t notice it until about halfway through the ep. It’s one of the coolest storytelling devices ever done on network TV.
