The Simpsons1989

Homer:
Save a guy's life, and what do you get? Nothing! Worse than nothing! Just a big, scary rock!

Bart:
Hey, don't knock the head, man.

Marge:
Homer, you don't do things like that to be rewarded! The moral of the story is that a good deed is its own reward!

Bart:
But we got a reward, the head is cool!

Marge:
Well, then maybe the moral is, no good deed goes unrewarded.

Homer:
Wait a minute! If I hadn't written that nasty letter we wouldn't have gotten anything.

Marge:
Mmmm... then I guess the moral is, the squeaky wheel gets the grease.

Lisa:
Maybe there is no moral, Mom.

Homer:
Exactly! It's just a bunch of stuff that happened.

Marge:
But it certainly was a memorable few days.

Homer:
Amen to that.
