This might be the first in-canon story comic to reference George's hair cut changing from time to time.
I changed it from his original spiked pompadour to the Skywalker inspired 'do in a 4th wall breaking strip
... but I don't recall mentioning the other changes I've done to the Skywalker or back to the spike. I could be wrong as it's been a little while since I've gone back through and read all of the archives.
But for those of you missing having zombies in Zombie Roomie... this arc is for you! There'll be more zombies in this storyline than there's ever been before!
