Homer: You Didn't Expect That, Did You. And Neither Will He.

Homer: You didn't expect that, did you. And neither will he.
Bart: You mean that I should fight dirty, Dad?
Homer: Unfortunately, son, we Simpsons sometimes have to bend the rules
a little in order to hold our own.
Bart: Amen!
Homer: So the next time this bully thinks you're going to throw a punch,
you throw a glob of mud in his eye!
And then you sock him [pounds fist into hand] when he staggers
around blinded!
Bart: [getting into it] Yeah!
Homer: And there's nothing wrong with hitting someone when his back is
turned.
Bart: Gotcha.
Homer: [quietly] And if you get the chance, get him right in the family
jewels. That little doozy's been a Simpson trademark for
generations. [punches the punching bag down low]
Bart: [cringes] Thanks, Pop.
