Float up stairs

From Glitches

From the game Animal Crossing for the Nintendo Gamecube

You need a 2nd floor and a basement helps. Go to the bottom of the basement stairs, but don't go in. Run up the 2nd floor stairs and when you are on the second step, your character will go up the stairs. However, you character won't run or walk but instead float up them.
