2. Wear red contacts to look scary.

3. Make sure you have plenty of bottled water. (In case you rant for a long time)

4. Wave your arms around. (Helps put your point across)

5. Have someone to back you up.

6. Have 9-1-1 on speed dial just in case things get violent.

And finally...

7. Make sure you actually have something to rant about...
