Speak on, fair child of my loi... er... my child

The other night Zach and I were laying in the bed talking, as if we were camping out under the stars, and he said, "Dad, I used to want to be a policeman when I grow up, but I think instead I want to be a Dad, like you."

To which I replied, "Here son, take this hundred dollar bill."

Actually, I gave him a noogie.

Now, tell me again why some people don't want kids? I... I just fail to understand.
