Also I forgot, whenever I'm at a bar, internet cafe, or anywhere that has a lot of items you can pick up (cups, billiard balls, etc.) I always pick them up and thrown them at people randomly. I knocked a nga out cold by throwing a donut at his face.
Shooting out tires in the ambulance is fun. After I enter a business and am done buying whatever, I always shoot the person in the face. Running down bikes is fun.
