I’ve always heard the expression “Don’t let me blow smoke up your ass” and never really knew where it came from. Do you?

Through hard research (Google) I found out it was actually a medical procedure used in the eighteenth century where, literally, smoke + tobacco was blown up a drowning victim’s bum to resuscitate them! Makes perfect sense, right?

Below, Stephen Fry and friends go into detail about the small bellows used to “revive” a drowned person.
