Judging that family, he's probably buried in the back yard.
Interesting to think of the various TV characters with numbers for names. Another that come to mind is 7 (from Star Trek: Voyager). Also, in the show Blossom, Blossom had a friend whose name was Six or Seven.
I think I'll do one with 5 and 6 and 7.
There was a character in Peanuts named 5. It was short for something longer. If I recall correctly, naming him 5 was his father's way of surrendering to the computerization of society and the associated reduction of people to numbers.
