“A lawsuit is something no one wants to have and no one wants to lose” is a popular legal contradiction that appeared in the American Bar Association Journal in 1920. “What is it that no man wants to have yet no man wants to lose?” was asked by the character of The Riddler in the television series Batman in 1966. “A lawsuit!” answered Robin, correctly.
