Otto

Otto is another one of Socko's unseen relatives whose name is a pun due to his occupation. He deals cars; his name is more of a pun because it is a homophone to "auto." He sells cheap rundown cars.

He sold a car to Spencer in the episode iGive Away a Car in which Nevel wins a car but it turns out the car was an old one, and Nevel refused it.

He is Socko's uncle.
