It all went down during a sit-down interview with Jeff Glor ... when Glor suggested he was not a moderate.
Nugent exploded, "I'm an extremely loving and passionate man, and people who investigate me honestly, without the baggage of political correctness, ascertain the conclusion that I'm a damned nice guy ... and if you can find a screening process more powerful than that, I'll s*ck your d**k."
Nugent then turned to Glor's female producer and said, "Or I'll f**k you, how's that sound?"
After the interview, Glor said Nugent's wife came out and told the former rock star that he needed to apologize. And he did.
