9009

Caiden had some friends over the other day and they were playing in the other room. Caiden came into the room where I was to show me what he had made. He proudly presented this paper saying "right now it's the number 9,009 but if I erase the comma then it's just nothing" (I guess he thinks it must have the comma).

Guessing what was coming next, I tried to be patient and to stifle my laugh. He said "But if you turn it upside down it says..." and he started laughing himself and couldn't say the word boob out loud.
