Used to be some gasoline had a proprietary antiknock compound in it called “Ethyl”. If I had been old enough to be a gas station attendant back then, and if someone asked for the gas with Ethyl in it, I would have been obligated to mutter “If Ethyl don’t mind!” and then spill gas on the side of their car. I saw the movie “Duel” again recently, and it reminded me.
I saw that movie when I was 13 and ever since then, my family has had to deal with me exclaiming “You can’t beat me on the grade!!” whenever driving uphill.
