More insidious than Tom's Diner!

It's one thing when you get a song stuck in your head. That happens to everyone. Just start humming the chorus of Tom's Diner by Suzanne Vega and watch what happens. But what happens when you get a book stuck in your head? I've had Goodnight Moon stuck in my head for the past couple of days. It alternates with But Not the Hippopotamus on my head's internal playlist. And there really isn't anything that you can do to get it out. At least with Tom's Diner you had a chance. You could always lapse into Yellow Submarine or YMCA in order to cleanse your head. But there is no dealing with Goodnight Moon.
