The ending of "Nuts to War (Part 2)" (where Earl tries to snap Robbie out of being a bloodthirsty warlord) is both this and a Heartwarming Moment.
Charlene Sinclair: [after the war is over] I heard that somebody got killed.
Robbie Sinclair: Yeah, it was some new guy... but you know we could've won!
Earl Sinclair: Robbie, what're you saying?
Robbie Sinclair: Well, I'm saying it's terrible that guy got killed and all, but you know we had those four-leggers on the run, we could've won it.
Earl Sinclair: A boy died, don't you see the fighting didn't solve anything?
Fran Sinclair: Come on, Robbie, let's get you out of that uniform, you have school tomorrow.
Robbie Sinclair: Forget school, a bunch of the guys were talking about keeping the army together if they came back, they'll set up a base at the swamp so we'll be ready for them next time. They're working on a WHOLE NEW line of weapons, yeah!
Earl Sinclair: Stop it! You're not a soldier, you're a kid,
[pulls Robbie into a close hug]
Earl Sinclair: You're gonna go to school, you're gonna take girlfriends to dances, you're gonna drive me crazy like you always have, until it's time for you to grow up.
[A small pause as Robbie comes to his senses]
Robbie Sinclair: Dad?
Earl Sinclair: It's allright son, it's over... you're home.
