Box of rocks, MSD

There is an expression here in the US, and probably in other english speaking countries, "Dumber than a box of rocks." Howard Stern has a quiz show on his radio show where he questions stupid people about obvious well known facts and they giggle and answer wrong. Our late night talk/chat shows have a ball during election years asking the average man in the street important topical questions, which they invariably get wrong. I saw British shows do it before Brexit.

So, finding this box of rocks by the side of the road, I put the expression to the test. It got three out of ten topical questions right. So the expression is correct. I almost removed the three correct answers when the box revealed that it voted for Trump.

Now I am off to find a bag of hammers.
