Yu-Gi-Oh! 5D's Easter Egg - Joey Wheeler

In the episode right after the one where Yusei loses his memory, watch and listen closely when Yusei, Blister, Tanner, and the old man are nearby a street duel. The camera quickly pans by a duelist and if you look closely, you will see AND hear that it is Joey Wheeler from the first series! Someone in the crowd says, "Is that Joey Wheeler?"
