Did you guys know at 8:22 the door in the background with the Greendale Community College symbol has a woman coming out of it and she wipes hers mouth and then seconds later a man comes out and zips his fly. The best thing about this is No one on the staff not the Cast nor the Crew or even the director of the episode knew about till after the episode aired.
Yeah, a few fans noticed it the day after the episode aired. It was later wmentioned in the DVD commentaries for the episode by the creator Dan Harmon and the director Robb Shrab. They both claimed they didn't know but I got the feeling they were hinting the opposite.
