A close second are the lawsuits via Lowering the Bar:
Bruni v. Bruni (Ontario Super. Ct. 2010) ("Here, a husband and wife have been marinating in a mutual hatred so intense as to surely amount to a personality disorder requiring treatment . . . . I am prepared to certify a class action for the return of all wedding gifts.")And many more
Noble v. Bradford Marine Inc. (S.D. Fla. 1992) (ruling, not long after "Wayne's World" was released, that "very excellent" authorities showed that removal to federal court was "most bogus and way improvident"; ordering defendants to "party on in state court.").
Moore v. Moore (Mo. Ct. App. 1960) (recognizing husband's right to fish without female interference, but ruling that minor infringements on it are not grounds for divorce; also finding that the term "hillbilly" is not an insult, at least when used in Southern Missouri).
United States ex rel. Mayo v. Satan and His Staff (W.D. Pa. 1971) (dismissing case against Satan and unidentified staff members for lack of jurisdiction and uncertainty as to whether case could properly be maintained as a class action).
