… you find, in mid-conversation with a friend, or on waking in the morning, that the theme song is running through your head. Even when the theme song is as good as this show’s, or when the show is as good as the one Lime and I have been overwatching. Even then, you know you’ve seen it too many times if the theme song is there and won’t go away.
I can end up with the theme song stuck in my head on just once-a-week exposure, if I do it for long enough. (Case in point, St. Elsewhere when I was in high school. Of course, I liked having it stuck in my head, so that wasn’t a bad thing. And one of the ways my parents were willing to bend the bedtime rules was, if the show started at my bedtime, if I just really, really wanted to hear the theme song, staying up just that little bit longer for that was OK, as long as I trotted upstairs immediately afterwards.)
