feather in one's cap

It was considered a feather in one’s cap to thump any elbow.

At five-and-forty, after knocking about the world for years, and "never opening a book," as people say, to have given a good "construe" is a feather in one's cap.

Have you ever heard any one speak of “a feather in one’s cap”?

"I think, sir, that it is not right to rob anybody of anything, and I reflect that absolute righteousness is a fine feather in one's cap."
