Watching it again, I thought of a few things I didn't the first time.
1) It really should have come out in the trial that George used Judge Vandelay's name. They set that up and then didn't go anywhere with it. It would have been great if the judge was about to let them go, then screwed them when he learned that George had been impersonating him.
2) I guess Big Stein had Mr. Wilhelm rescued from the carpet cleaning cult, since he was there at the trial.
