If you've never seen the episode, I can see where someone would be like WTF? The episode's Koogler character was this off-beat, throwaway cameo appearance that wound up being one of the more delightful things about "App Development and Condiments."

There's even a mock 80's trailer at the end of the episode advertising some kind of Back to School / College Party film. So much awesome! I think overall, it's in my top 3 favorite episodes of Community.
