Flat Character: Much of the supporting cast beyond the main four guys, Jessie and Kimmy. Heck, Rocko and Cal are usually just there for quick gags, and are too dumb for major depth. Jessie even lampshades this when describing the guys she hands out with in "New Friends."
Jessie: Relax, these guys are easy to get to know. Brody is always full of crap.
Jessie: Krueger has one response...
Krueger: Fuck DreamWorks.
