Sideshow Bob, "But wait, if you saved Selma, why did the room explode?"
Chief Wiggum: "Me and the boys were celebrating a job well done," [cut to Wiggum, Homer, and a few cops smoking cigars] "When I threw my match in the vicinity of the crime scene."
The police start to take Sideshow Bob away, and he yells, "I'll be back. You can't keep the Democrats out of the White House forever. And when they get in, I'm back on the streets, with all my criminal buddies!" (Maniacal laughter).
