During the '80s, my family received a Radio Shack catalog in the mail with no first name of the intended recipient. There was just the initial R followed by our last name. None of our first names start with R, so Mom did the logical thing and asked our cat, "Rusty, have you been ordering stereo equipment?"
I'm still not sure how to decipher Rusty's meowed response. Jazz and swing guitar tunes got his tail tapping, though, so it's possible that he wanted to hear them in surround sound on speakers with the proper balance.
