New Life Goal, And It Involves Me Becoming A Crazy Pet Lady. Which I'm Fine With.

I need to ultimately own four pets, purely for the names I have devised:

Regina Phalange (check)
Arf Vandelay, Vandelay Industries
Bob Vance, Vance Refrigeration
Anastasia Beaverhausen

And if any of you can tell me which one of these things is not like the other, you win the prize of my adoring affection.
