First get a Bobcat. Then type in the cheat for Cars float away when hit (on this website).

One of you climb into the Bobcat and just sit there. The other one should get a Sanchez.

Speed toward the front of the Bobcat. When you hit you will fly over you handles and land on the hood. The car will then float away.

Player 2 will be sitting safely inside the Bobcat. Player 1 will be standing on the hood.

You will Float away untill you just see a glitch in the sky.
