Rob appeared in the episode 'iGive away a Car' for only a few seconds.
Rob is Socko's cousin. His name (like almost all of Socko's Family) is a pun on his occupation. He is a robber. He helped Spencer get his couch back, in the episode iGive Away a Car. He was one of the few relatives of Socko's to be seen. After stealing the couch back, Spencer gives him 50 bucks and says, "Thanks Rob!". Rob responds by doing a tongue click, and leaving the apartment.
