Bart and Marge in “The Boy Who Knew Too Much”

Bart

Mom, what if there's a really bad, crummy guy who's going to jail, but I know he's innocent?

Marge

Well, Bart, your Uncle Arthur used to have a saying: "Shoot 'em all and let God sort them out." Unfortunately, one day he put his theory into practice. It took 75 Federal Marshals to bring him down. Now let's never speak of this again. [she then starts humming and dusting the TV]

Bart

Mom, what if I can get this guy off the hook? Should I do it?

Marge

Honey, you should listen to your heart... and not the voices in your head, like a certain uncle did one gray December morn.
