Can "self" crush itself?

[n00m]

aaah... globals()...
Then why "self" not in globals()?

class Moo:
    cnt = 0
    def __init__(self, x):
        self.__class__.cnt += 1
        if self.__class__.cnt < 3:
            self.x = x
        else:
            print id(self)
            for item in globals().items():
                print item

f = Moo(1)
g = Moo(2)
h = Moo(3)
