Why does a delegate with no parameters compile?

I'm confused why this compiles:

    private delegate int MyDelegate(int p1, int p2);

    private void testDelegate()
    {
        MyDelegate imp = delegate 
        {
            return 1;
        };
    }

MyDelegate should be a pointer to a method that takes two int parameters and returns another int, right? Why am I allowed to assign a method that takes no parameters?

Interestingly, these doesn't compile (it complains about the signature mismatches, as I'd expect)

    private void testDelegate()
    {
        // Missing param
        MyDelegate imp = delegate(int p1)
        {
            return 1;
        };

        // Wrong return type
        MyDelegate imp2 = delegate(int p1, int p2)
        {
            return "String";
        };
    }

Thanks for any help!
