Kakashi to genin Team 7, who were all lounging around his apartment: I'm going to go to the store right now and until I get back please do not commit any war crimes

Sasuke: No promises

Sakura: I wonder how the Hidden Mist looks this time of year

Naruto: And how could we make it look with some paint, tooth paste, and ninja wire?

Kakashi, leaving without looking back, knowing he's going to regret this later: Don't get arrested.
