This episode is 'Totally Unobjective'. A show where Chris and Zach give completely biased top 5 lists based on nothing but their wildly biased notions of reality!

This week Chris and Zach insult each other for your pleasure, like gladiators of yore, but without all of the actual fighting, and blood, and sandal wearing.

(It's entirely possible that Chris was secretly wearing sandals during the recording of this episode. He's tricky like that.)
