You know the theory of cell irritability? If you take an amoeba cell and poke it a thousand times, it will change and then re-form into its original shape. And then, the thousandth time you poke this amoeba, the cell will completely collapse and become nothing. That's kind of what it's like being famous. People say hi, how are you doing, and after the thousandth time, you just get angry; you really pop.
