Oh no! Another grammar thing that irritates me! So what else is new!
I dislike the sound of this construction so many people seem to use: They say “based off of†when they mean “based on.†Just ran across it for the millionth time lately:
“We base the market prices off of public auction sales…â€
But it does remind me of a funny routine of David Steinberg’s, in which he recounts the story of Moses encountering God for the first time, and God tells him to remove his sandals because this is holy land he’s about to step on:
"'Moses! Take your shoes from off of your feet,' God said in his redundant way.â€
So Moses does, and walks towards the burning bush, scorches his feet, and swears. (This was the first mention of Jesus Christ in the Bible.) God laughs and says, “Hah! Third one today!â€
