Garfield: You would have been 30 but you were sick a year.
Jon: I would have been 30 but I was sick a year.
Garfield: MY KINGDOM FOR A NEW PUNCH LINE.

Jon reveals his age! This information would come in handy on July 28, 2003 when his actual birthday is revealed. Buf if he was 29 in December of 1980, that would mean his date of birth was July 28, 1951 – not July 28, 1950.
