Bob Odenkirk is actually an alien. He came into being when a giant dropped its eggs. One egg was a left arm; another, his right. When all the eggs hatched, there was enough to make a full creature. The pieces of Odenkirk rolled around until they, one day, found how they fit together (you can see why his species have such a high infant mortality rate).
Bob, once he became more than just a mass of parts, shunned the technology of his people. He left the lasers, escaped the electronics, and abandoned the androptogons* for simpler things. Human things, like slingshots and comedy. He desperately wanted to experience the rush of both.
Odenkirk’s alien race doesn’t understand comedy. Or slingshots. Scientists who know their shit believe their lack of knowledge of these two things led to the extinction of his species. Bob Odenkirk is the last of his kind until he lays his eggs.
*An androptogon is a medical device used to restore the surface of an exoskeleton. It was invented by Bob’s alien race and hasn’t been invented on Earth yet. Pretend you know nothing of this if anyone “official” asks you.
