Bumbling, inappropriate, and bizarrely accident-prone, Hitchcock is the show's secret, shameful weapon. We're used to seeing him bring pain entirely on himself, but in this skit, he's merely the innocent victim of Jake's diabolical scheme to make the older detective pee his pants. Well, as innocent as Hitchcock gets, anyway — let's not forget that he falls asleep in the break room, facedown on the table.
Jake relies on the tried-and-true summer camp method for his prank, leaving Hitchcock's hand in a bowl of lukewarm water. Jake immediately brags about his joke to the squad. When they check on the pee progress, Hitchcock is somehow facedown in the water. Killing Hitchcock wasn't part of the plan, and they grab him in the nick of time. In Rosa's opinion, this macabre turn hugely improves the whole situation. "I take it back, Jake," she says, actually smiling, "great prank." If Rosa thinks it's funny, then you know something's gone sideways.
