Eleven.

This child gets his incredible good looks and unfortunate attitude from his Mama. Beyond that, I can't take a whole lot of credit.
Not very long ago, he was a newborn, and today he claims to be eleven years of age - and while that is totally implausible, we have to believe him because he is a 100% truthful and accurate sort of person. His grandfather says that if Seamus told him there was a rhino in the driveway, the only question he'd ask is: What color is it?
