Because nerds can't help over-analyzing stuff to death. Seriously, you're on a message board called "Toonzone", you should know this already.

Seriously, the only CN shows I can see being in the same universe are Dexter and Powerpuff Girls; and even that is a bit of a stretch. Back in the late 90s/early 00s, a very small group of people worked on virtually every original show on Cartoon Network. So it's not surprising that a lot of similarities, cameos, inside jokes, and shout outs happened.
