I honestly can't remember a bug in a first party Nintendo game. Might be just my memory though :P
Maybe Xenoblade? I remember that sometimes arts I selected didn't get used even though the sound played off. Not sure what's up with that.
Edit: I know you can find plenty of "bugs" in forexample Mario Kart and Zelda, but from my experience these have to be forced, so Idon't count them (never seen them on anything but youtube, and what you have to do to get the glitches is pretty darn insane most of the time.
