If you dial these numbers correctly, you will usually get someone on the other end of the line that you can subsequently prank.
If you boost a fire truck, press the fire button while driving around. This will allow you to shoot the super-powerful water cannon at anyone around you. Watching people react to getting shot with high-speed water is just utterly hilarious.
Statue of Happiness
Head to the Statue of Happiness on Happiness Island with a helicopter. Have the helicopter drop you off on the very top of the statue. You'll find a sign up there that states "No Hidden Content Beyond This Point", but it is actually a lie. If you head inside of the statue from this area, you'll find an actual beating heart inside the statue. How ridiculously creepy is that!
Fire trucks are awesome vehicles to use to cause complete and utter destruction in Liberty City. But, even these vehicles are susceptible to damage. Oddly, if the fire truck catches on fire and is about to explode, you can actually utilize the fire truck's very own water source to put its own fire out which is just amazing and also makes the fun last longer in the fire truck.

How To Gain Money Easily
Head to an ATM anywhere in the city, and cause traffic jam in the area. Wait for someone to approach the ATM and take money out of it, and then eliminate that person. The traffic jam should ensure that no ambulance can reach the injured person, so if you run a short distance away and return, you can grab the money that dead person dropped over and over again.
How To Get Free Taxi Rides
Here's a great way to get a free taxi fare. Hail a taxi and get inside, and head to your destination. Right before you get to your destination, bust out the back window and point your gun out of the window (using the corresponding controls). Doing so will freak the taxi driver out. He'll stop the car and run away, leaving you near your destination without forcing you to pay for the ride.
