Zombie Steve Jobs of course! He’s returned from the grave to steal the buttons off of your electronics!
Seriously, this will be one of the easiest costumes to make, as all you need is a turtleneck, glasses, a beard and your iPhone. I think this would actually be a funny “too soon” costume however, unlike some I’ve seen like a guy in a bloody Virginia Tech sweatshirt that I almost had to punch in the face out of principle.
But no, I’m sure Jobs would look down from Nirvana (he’s Buddhist) and laugh a bit at your hilarious costume. Or he might come back to earth and crash your Macbook hard drive.
