Whislt I don't like this episode and choose to ignore it, I have recently watched Bad Dare Day (the following episode), and at the end Bloo (impersonating Mac) mentions him being eight years old- unless he was just mistaken, this would perhaps be proof of your theory. Well, we can believe what ever we want.

Or it could be just CN airing the episodes in the wrong order. Perhaps Bad Dare Day took place before Bloo Superdude and the Great Creator of Everything's Awesome Ceremony of Fun That He's Not Invited to.

Just a thought. XD

Actually, considering how old Mac is, he was eight in 2004, making him born in 1996 (hey, same year as me :D), so wouldn;t he be 12 or 13 in that episode?

In real life logic, yes. But in cartoon logic, not necessarily. The same has happened with the cartoon "The Simpons". Lisa would be close to 30 by now, but nope, in the latest episodes she's still eight. Another is "Arthur", which debuted in '96 I believe. Arthur is eight when it debuted, and new episodes are still being made today so he'd really be 22, but nope. He and his friends are still eight. In fact, I think most cartoons don't really age their characters other than a few episodes where a birthday is mentioned. It's just cartoon logic. It can be hard to get use to, but as long as you don't obsess over it and analyze things too much, we can live with it.

Hmm, I just realized eight is a popular age for cartoon kids, too.
