Monogram said in Agent Doof something about the number 2000 and Doof goes "2000? That's so 4,000 days ago" which is, from right now, early 2001. Plus, Troly got an answer from Povenmire, who asked what year does it take place, whatever year the episode's made. I also back that up because the time machine thing in The Best Lazy Day Ever 20000 BC 2008 98000 AD. That episode was made in 2008. We're getting so many hints about everything about the group now!
