- In episode 14, Yusuke brags to Kuwabara that he beat Hiei on his first case. This was most likely a subtle insult to Hiei as being so weak he was beaten by a kid with virtually no training or experience. Hiei's excuse was that he was recovering from surgery and that the "extra eyes don't grow themselves". This might just seem like a lame excuse unless you know the history of Hiei's Jagan eye in the original series as being surgically implanted and causing his massive drop in power from being originally an A-class demon to a D-class demon. So Hiei wasn't just making excuses for his first loss and props to Lampinator if that was intentional.
- In the 18th episode of Yu Yu Hakusho Abridged, after the episode ended guy that voiced Yusuke asked why Seiryu the Dragon was dubbed with a Hank Hill accent. He responded, "Because I'm a dealer of strict and cold pain". Not being a fan of King of the Hill, it took me a few years before I learned Hank Hill worked at a place called Strickland Propane.
