Grover's law, an analogue of Godwin's law, states that whenever one Internet user accuses another of being a "sock puppet" (i.e. fake identity) without proof, the argument is over and the accuser has lost the argument.

The name of the law comes from a diagnosed paranoiac's belief that all Internet posts originated from the Sesame Street persona Grover.
