The Equivocation fallacy is used when the conclusion of the argument depends on a shift in the meaning of a word or phrase. In Abbot and Costello's "Who's on First?", the entire argument stems from the basis that all of the player's names on the baseball team are words that cause equivocation fallacies. For example, if Who is on first, and you want to know who is on first, there is going to be confusion.
