Do you ever have a sudden vision, while in a public place (usually a store of some kind) of yourself in a musical that takes place in that store? And actually you are the only person in the musical? And you are singing at the top of your lungs, really belting it out, and dancing and spinning down the aisles? And then that vision turns into an uncontrollable urge? This has happened to me 3 times this week. So far.
