Batman - Season 2 Episode 29 : The Cat's Meow 1968

The Catwoman "steals" the voice of a television talk-show host in the middle of an interview with Bruce Wayne. She plants clues to suggest either the Joker, Riddler or Penguin may have committed the crime. In the meantime, she has fooled Commissioner Gordon into thinking she has gone straight. She makes her first mistake when she masquerades as Miss Klutz, a dance instructor visiting Wayne Manor. Allergic to dogwood, she sneezes and gives herself away. Her next target is to "steal" the voices of British singers Chad and Jeremy. Batman and Robin eventually track her to a dance studio, where a fight erupts. After it appears the Dynamic Duo has triumphed over Catwoman's forces, she drugs them. The heroes are placed inside a chamber where the sounds of water dripping will be magnified many, many times and drive them insane.
