10. Heart Of Liberty City (GTA: IV)
The Statue of Happiness is an Easter Egg in its own right, what with the obvious reference to the Statue of Liberty. The only different being, the statue is wearing a huge smile and is holding what appears to be a cup of coffee in the place of the famous torch. (Possibly a sarcastic reference to America's coffee industry with Starbucks popping up left right and centre these days). However, it's what is inside that comes as the biggest Easter Egg here. First, you need to commandeer a helicopter and tilt it ever so slightly so that you can jump out (unharmed) onto the upper platform of the statue's pedestal. If you manage that, you will be greeted with a hilarious message reading "No Hidden Content This Way" (they're lying). Walk through the door and climb the giant ladder to the top, and there you will be greeted with a giant beating heart - the Heart of Liberty City.
