Bart learned that ray guns were being hidden in Duff Trucks, so he rammed one of the trucks with his car as it was leaving the brewery and collected the guns. He also found a gun next to the blimp. He showed the guns to Krusty to prove that aliens were using them as part of a conspiracy to control human behavior. Later, Bart learned that Kang and Kodos were at the brewery, so he and Homer raced there against a Chase Sedan and encountered the aliens emerging from the brewery inside their spaceship. Before flying off, the aliens revealed their plans to raise the dead to boost ratings for their reality TV show Foolish Earthlings.
