WTF am I doing...? (Please ignore this gist, It's just a drunk code)

World.cs

using System;

internal class Human

    private string name;
    private Hand[] hands;
    private Human()

    {
        foreach (Hand hand in hands)

                return hand;
        return null;
    }

        Human me = new Human("LuviKunG");

        else
            Console.WriteLine("And why I can't show my middle finger!? So sad...");
        if (hasParams)
            Console.WriteLine("I don't even care about what are you sending params!");
        Console.WriteLine("Welcome to C#.");
        Console.ReadKey();
        return hasParams ? 1 : 0;
    }
}

My life is done.
