Bug: A rather infamous shortcut glitch is in Wario Stadium, where the very first hill after the starting line is high enough that if you hit it at an angle you can completely jump over the wall. This cuts off a significant portion of the track, putting the player way ahead. Then on top of that, if you turn around and hit a part of the wall just right at a good angle, it will cause you to jump back over the wall before the finish line, cutting off the full track. Do it right, and you can complete the full three laps in under 30 seconds.
