In "Card Sharps", Lamont gets duped by a bunch of card sharks that pretend to be his friends. Fred, experienced in this sort of thing, attempts to tell Lamont that he's being screwed out of his money. Finally out of money, Lamont gives up. Fred innocently asks if he can play with them. One Gilligan Cut later, and Fred has not only completely cleaned them out, he's done it by cheating better than they could.
