Wrong game
From Glitches
From the Computer game Mario's Fundamentals.
On the main screen, click on the game. Then, quickly choose another game. Mario will name the first game you chose, however you'll end up playing the second game you chose. For example, click on Dominoes and then Checkers and he'll say something like, "Great, dominoes!" and flip some domino pieces, but then the checkers screen will come up.
