The forbidden phrase was "I don't know." Also bad juju was saying "water", as that would cause the wet stuff to come pouring down on you. So far as I know, Nickelodeon's first big television success, shortly followed by Double Dare and other weird game shows for kids.

Also frequent were Barth the disgusting chef and the execution squad leader.
