Remember when Community's Abed delivered a baby in the background of Season 2's "The Psychology of Letting Go" and we (read: "the internet") all went bonkers over it? Wait 'tll you see this.

The following video includes clips from Season 1's "[insert episode title I couldn't immediately place," Season 2's "Cooperative Calligraphy," and Season 3's "Horror Fiction in Seven Spooky Steps." Beyond that, all you need to know, if you're not familiar with the seminal 1988 comedy horror film Beetlejuice, is that if you say the titular ghoul's name three times, he appears. Watch very, very closely.

Dang, those guys are good.
