Get a heli and the health/repair cheat ready on your phone.
Then go to a street with alot of trafic(Star junction) and and stay just above ground,know start tilting the heli
towards the cars and peds. and have fun throwing them way in to the air like a superhero, police cars will xplode when they come down.
You can repair the heli with the cheat to stay alive, wery amusing for a couple of hours...
