In Pokémon Gold & Silver, there's an apparently foreign person called Earl, who has rather weak English skills. He speaks sort of like Yoda.
His greatest line: "What you want to know? Want to be a winner is you?" (emphasis mine.)
I think Nintendo put that thing there on purpose for us old NES gamers, but I don't think the kids today get the reference =)
Jay Digital says: "A winner is you!" was an old alt.games.nintendo.pokemon injoke at the time. A few of the people there had connections to Nintendo - rumour has it that they snuck in the reference as a tip of the hat to the newsgroup. The line specifically was in all capitals, "A WINNER IS YOU", and was used in the newsgroup as an (often sarcastic) phrase of congratulations.
