Abed Delivers a Baby in the Background
In Season 2’s “The Psychology of Letting Go” there’s noticeably less Abed in the story. However, you can see him in the background having his own separate storyline. First he meets a pregnant woman, then that pregnant woman’s man hostilely confronts Abed as if he suspects cheating, then later we see Abed helping deliver the pregnant woman’s baby.The detail here is remarkable because the first time the couple was shown in Season 1, the guy is carelessly tossing a condom aside. Many months later, in Season 2, the woman is pregnant.
Beetlejuice, Beetlejuice, Beetlejuice
Talk about dedication – this joke played out over a span of three seasons. Once every season, someone would say the name Beetlejuice. Of course, saying his name three times is the way to summon him, so after being mentioned on Season 1’s “Communication Studies” and Season 2’s “Cooperative Calligraphy” we finally see Beetlejuice appear in the background when Annie says his name in Season 3’s “Horror Fiction.”
Annie's Stolen Pen
In season two’s eighth episode, “Cooperative Calligraphy,” Annie’s pen goes missing and the group searches for it. If you pay close attention though, you’ll see that Annie’s Boobs, the kleptomaniac monkey steals her pen, which is later found in his stash of belongings.
