In this episode the Planet Express crew are watching a supernova and end up time travelling back to the 1940s in Roswell. Bender's Body and Zoidberg are captured, Farnsworth and Leela go looking for a Microwave to return to the future, and Fry tries to prevent his grandfather Enos from gettin killed. In a bizarre twist, he ends up killing his grandfather in an explosion and ends up sleeping with his grandmother, sickening the others. After screwing up, the crew steal the Microwave dish, escape, and find Bender's head 1000 years under the desert. Funny, touching, well written, and disgusting. Roswell That Ends Well has it all!
