From the game Banjo Tooie for the Nintendo 64.
In Terrydactyland, go to the River Passage as Banjo alone. Now, use the Sack Pack (Z + C up) and float along the river, holding Z the whole time. As Banjo reaches the waterfall, he won�t fall down. Instead, he�ll start floating upwards, and after a few seconds he�ll jump out of the backpack and fall down.
