Some of these references happen early in the anime, but the most recent for me (because I'm watching the dub) is episode 94, Keeping a Promise Part 1. Someone made a joke about Seto Kaiba--it was so random it made me laugh. XD I can only remember references to Seto Kaiba's influence on dueling technology, which makes me think he's the sole character referenced.
