Sideshow Bob: Oh! I renew my objection to this pointless endeavor! informally now and by affidavit later... time permitting.
Chief Wiggum: Shut your wordhole! We gotta get this place clean for the air show.
Sideshow Bob: Air show? Buzz cut Alabamians spewing colored smoke from their whiz jets to the strains of "Rock You Like a Hurricane"? What kind of country-fried rube is still impressed by that?!
Sergeant: Authorization code?
Sideshow Bob: [impersonating Colonel Leslie Hapablap] Code!? Son, this is Colonel Hapablap. That fool McGuckett sprayed runway foam all over Chuck Yeager's Acura. Now get down there with the chamois triple time!

Homer: Well, I wrecked the gate, but you don't hear me bragging.
Sideshow Bob: Ah, for the days when aviation was a gentleman's pursuit back before every Joe sweat sock could wedge himself behind a lunch tray and jet off to Raleigh-Durham.
Bart: [spitting] Are you getting lots of bugs in your mouth, too? [spits]
