Fry and the Slurm Factory on Futurama
Twentieth Century Fox
In "Fry and the Slurm Factory," Futurama spoofs Budweiser spokesdog Spuds MacKenzie and Charlie and the Chocolate Factory. The opening shows an ad for a Slurm contest, featuring Slurms MacKenzie. Fry wins, and he, Leela and Bender visit the Slurm Factory. The Grunka-Lunkas (Oompa-Loompas) greet them with their song. But Fry is so thirsty, he falls into the river of Slurm. Leela jumps in to save him, and Bender jumps in just because. The three of them are sucked into a whirlpool which drops them into the real factory. They discover the source of Slurm: it shoots out of the butt of the giant worm Slurm Queen. They are discovered, but Slurms MacKenzie helps them escape. Fry never tells anyone what Slurm is made of, because he is so addicted he doesn't want production to stop.
