Since I was a math major I was able (with the help of a calulator) to determine that your grandson was 4 when he noticed that the name on TV and on your sign were the same.
Pretty dang smart, I'd say.
Yes, he is. He is on the school Spellbowl team, and consistently brings in straight A's. His sisters are also smart. The older one has been reading since age 3, and the youngest (who will be four in November) is able to navigate the NickJr. web site to play games, and can type in her name on the games.
Smart people vote BUSH! LOL!
