I guess it's about time the law caught up with one of Roger's Personas.
This episode had some good jokes: the guy trying to have sex with the street performer, Stan's list of fictional dogs (Brian being #1, but he shrugs him off), and the family trying to deal with Jeff's disorder.
If Stan didn't assault the marshall and just went after Roger, he wouldn't have to be on trial. Now Roger's going to screw him over.
Since Stan included Brian in his fictional dogs list, that cements Family Guy as a cartoon in the AD! universe.
