I thought it would be a good idea to make a thread we can all add the little tips and tricks we have found that others may not know of. I'll start with a few.
1. Press right on the directional pad when around pedestrians to strike a conversation.
2. Tap L1 (PS3) or LB (Xbox) while in a car, and while unarmed, to speak to pedestrians when near. Hold the button to give the middle finger.
3. While unarmed, jump forward and then immediately press Circle (PS3) or B (Xbox) to do an intentional fall. This one can be really funny.
