This is the stethescope that the nurses and doctors listened to you heart with when you were a teeny tiny little baby in the hospital. We were instructed that everything in the hospital room was ours to take except for the linens, so it got shoved into a bag of loot (along with some linens) and brought home. Then it found its way into a toybox, and now you carry it with you everywhere. I'm not quite sure what you think it is, but man, is it fun.
