This isn't so much misheard as misunderstood. I thought the line "And hamsters turn on frequently" from Simon and Garfunkel's "At the Zoo" was talking about robotic hamsters that could turn on and off with a switch. My dad told me the song was about the Central Park Zoo in New York City and I always wanted to go to New York to see the hamsters turn on and off.
