My father-in-law had to educate the expert about a rifle brought back from the war.
He didn’t make the cut when it came to being televised.

My father-in-law had to educate the expert about a rifle brought back from the war.

No one knows everything (after being a teenager). What rifle in what war, if you recall?

I've been surprised how knowledgeable the "Pawn Stars" staff are on their show. If they don't know something they have a cadre' of experts on call.
