Top 4 things to do on your trip

4. Go into a gas station angry. Insist that you were there an hour ago and the clerk gave you bad directions.

3. Pull up beside another motorist. Leaving your window up, yell and motion at the motorist that there is air in their tires.
Look very concerned.

2. Pick up a hitchhiker. Claim that you know who he is and that you will not let the FBI find him. Mumble something about taking him to a safe place in the desert where nobody can find him.

1. Pull up beside someone. Have your passenger splash ketchup on his window, slam his head against it, and slowly slide his head down the window.
