Here's the Superman glitch:
1. Go to Bunnyhill, but quickly open up your map.
2. You should have your map when it asks you, "Would you like to join this Sled game?". Click yes.
3. Once the game starts, click the Town.
4. Press the "w" key and you should into the top left hand corner of your screen!
That's first glitch posted(and that I learned)!
