Clash of the Cousins is the second of segment of the 44th episode of The Adventures of Jimmy Neutron: Boy Genius.
Jimmy is shunned at the Neutron Family Reunion and is framed for almost getting the family killed. He finds out that his Cousin Eddie is the culprit and not only is he a boy genius too, but he's evilly plotting to do away with the entire Neutron clan for Aunt Amanda's fabulous wealth. Can Jimmy stop him before he's an orphan?
- One of Jimmy's relatives is an animate caricature of Keith Alcorn (one of the franchise's creators).
- Granny Neutron wasn't at the reunion because she's in Reno kicking butt at a casino.
- Eddie is similar to Stewie from the Family Guy franchise.
