(S01E03) "Now that's what I call moving some merchandise." - John Casey

If you've already seen the episode, which I assume you have, you'll know the quote above comes at a very tense point in the show. The writers had two ways to go: have Casey say something very serious or have him say something so ridiculous it counters the "bad-ass"-ness of the previous scene (i.e. a microwave straight to a thug's head).
