Another I consider an all time classic is when Harry Aleo expressed a mixture of disgust and confusion at the idea of comparing ownership of Lost in the Fog to the "Battle of the G**D*** Bulge" on live national television. Was that to Quint Kessenich? Someone with standards and practices probably had some serious acid reflux with that one.
