UPN made thirteen episodes of this show, and only twelve aired. The unaired episode was titled "The Ex-Girlfriend".
The Car Mechanic's weakness, is his reflection in a mirror (he even tapes up the rear-view mirrors on his own car).
The Boss is based on Gus' boss, who fired him for working on his video game. His weakness is red ink. Red ink (in the red) signifies losing money. There was nothing his boss hated worse than losing money.
The Sebastian Jackal's weakness, is the autographed baseball that Gus got from Bobby Mercer at the one game he ever went to with his father.
