This is the best egg I have ever found in my entire life!

Select the "nutopia" track and choose any car or character. I do recommend "sabre" though.

Press race.

When the game loads, drive your car and keep driving.

When you get to the jump before the "dam" drive as fast as you can to get onto the other ledge.

If you don't make it the first time, finish off that lap and try again.

If you continue to fail, get to the jump again and just before you reach the jump, type in "icbm" and you will make it onto the ledge.

Drive until you reach a "dead end".

You will find the "suck" cheat, a sign on the barrier saying about nutopia and a picture on the wall of all the people who made powerslide!

Now you know why it's the best easter egg!

Good luck!
