I war a thickhead too never to have thought of it.

“There’s some hope for a thickhead, but there isn’t any for you.”

Out on me for a thickhead for not linking thee with that bold feat before.

You don’t suppose that thickhead would have the gumption to do what this chap did, or the wit to know about paper being a non-conductor, and all that?
