Despite airing before Law and Odor, the Stink Bug is seen in the T.U.F.F. Prison. This episode may have taken place after Law and Odor as it says that it takes three to five years before D.O.O.M. gets out of jail.
When this episode premiered, it was played after Law and Odor so viewers could get an idea of who the Stink Bug was at first.
Larry already has the M medal on before he changes his name to Murray, this may not be a goof as it may represent something else like Mayhem.
