It brought back memories of a lecture I had back in medical school, when a cardiology professor delivered these helpful quotes:
"This type of murmur sounds like a snowflake landing on a feather."
"You can practice mimicking heart sounds by tapping on Kleenex."
"If you think you heard this murmur, you didn't."
"I've never heard that heart sound, so I don't believe it really exists."
"If you can imagine the sound dandelions make as you blow seeds off them, you should be able to hear this murmur."
