On World Domination

Stewie's question would seem harmless enough, if the sinister plot of the WWCTSRCNRIN didn't come to light just yesterday:
Q:"Can I take over the universe after I take over the world?"
A: I need some background information, Stewie - how sure are you that you will take over the world? Have you practiced on smaller things? Have you taken over at least a bathtub? How about a small country, let's say the Vatican - anything that size? It would improve your chances dramatically. Also, if you're having trouble, you might want to enlist the help of someone more experienced. Say, Jesus. Of course, he'd probably refuse to help you if you've attempted to besiege the Vatican. Best of luck.
