I've heard that one named Ashton is an adult. But he's too busy with Kroze.
I think it was likely more of a script idea, but I could be wrong. I just remember that James did watch a full episode during Desert Bus and said something along the lines of it wasn't bad but it wasn't that amazing. Of course, that was just one episode of the show. It's entirely possible he watched more and grew fonder of it.
Personally, I'm in the 'it's pretty OK' party. The way I put the show is that it's good enough where I want to watch the rest of the episodes, but not good enough where I've actually gotten around to doing so.
Either way this was a pretty good episode. Dealing with more pony-related stuff was only really made worth it by the porn and 'really chunky' jokes. And I'll always have Pony Glue to fall back on.
