Trivia: Yin Yang Yo!
- Fan Nickname: Some have given Yuck's nicer personality in "Upstanding Yuck" the name Oliver; also, Yin's evil side in "Gone A Fowl" is sometimes called Eve.
- Hey, It's That Voice!: Seth Macfarlane is the Manotaur.
- Talking to Himself: Yang and Yuck are both voiced by Scott McCord, could be justified in that Yuck is half of Yang and it would make sense for them to sound similar. The same with Dave and Coop who are both voiced by Dwayne Hill.
