Foul Bull is the first segment of the 35th episode of The Adventures of Jimmy Neutron: Boy Genius.
During a class trip to a rodeo, Jimmy, Carl and Sheen fall for a cute cowgirl, Sagebrush Sally. To prove themselves worthy of Sally's heart, each of the boys set out to master a specific rodeo talent. Sheen turns himself into a rodeo clown, and Carl wrestles a pig, but it's Jimmy who comes out the victor with his impressive bull riding and fool proof robotic bull, of course. Once Sheen causes the bull to malfunction however, the boys need the help of a real cowboy to save the day. That cowboy, or cowgirl, turns out to be none other than Miss Fowl.
- We learn that Ms. Fowl used to be a cowgirl.
- Libby starts to figure out Cindy's true feelings for Jimmy.
