Yoshi egg slide
From Glitches
From the game Super Smash Bros. Melee for the Nintendo Gamecube
Have one player be Yoshi, the other be Samus. Have the Yoshi player hold his shield, where he is encased in an egg. It doesn't matter how hard or soft it is, as long as it can be held for a long enough time for the Samus player to use a forward+a smash on the Yoshi while it's shielding. When this is done (this usually works a lot better with about 100%-140% damage), the Yoshi will slide across the stage.
