It turns out that Nick is the best undercover officer in Zootopia; the old stereotypes work to his advantage, even though he hates to be, even for a moment, just what the criminal thinks he should be.

Judy is the opposite -- she just stands like a cop, her foot tapping, her encouraging smile too obvious -- to the point where he really has to improvise in order to carry off this sting.

"You told them I was what?" Judy screams after him as they bolt down the street, hooves pounding behind them in pursuit, and honestly, Nick is pretty glad that he's too busy trying to catch his breath to try to answer her: what did she expect, putting a fox in charge?
