Fun story: As a child, I was confused whenever “knock out gas” was featured in cartoons or movies. I assumed they meant liquid gasoline, since that was the only gas that I knew of at the time. So whenever I thought of stories in which women were put to sleep by “knock out gas”, I imagined they were having sleep inducing gasoline injected into their bellybuttons. What can I say, I was a dumb kid with an overactive imagination.
