The stethoscope I cho'

I was bored to death in the clinic, so I took a seat and started to twirl my stethoscope. I was mesmerized by the motion of the chestpiece going round and round and round. As expected, an equally immature toddler also fell into the trance. So much s...o that he ran up to catch it. And, also as expected, it hit him straight in the leg. But on the bright side, no murmurs, gallops or rubs.
