A very good episode with clever writing and a unique storyline. The entire episode was brilliant, and I loved the romance with Leela and Fry, as I always do, of course. The adventure inside of Fry's body was excellent. I enjoyed the episode from start (the theme song) to finish (the end credits, of course). I recommend this episode to anyone who likes the show, and who enjoys the relationship between Fry and Leela.
After Fry eats an egg salad sandwich from a gas station, he gets parasites. His personality changes for the better, causing Leela to fall for him.
