Rush invites Dingy on the show to face him like a man. “Have you no shame or decency left???”

[Cracker Jack]

From the Army-McCarthy Hearings, June 9, 1954:

Mr Welch to Senator McCarthy: "Have you no sense of decency, sir, at long last? Have you left no sense of decency?"

This was the source of the phrase Rush used at the end of his challenge to Reid.
