During a game one day, NFL official Art Holst threw a flag after a linebacker tackled legendary Jim Brown. "I threw the rag and stopped the clock," Holst recalled, "and told the referee, 'I got #55 on the defense, pulling the facemask, personal foul, 15 yards.' About that time he [the linebacker] jumped up -- all 6'6", 260 pounds of him. He looked down at me and said, 'What?' I said, 'Get back in there and play football before I bite your head off!' They're all real good guys and very politely he said, 'If you do, sir, you'll have more brains in your stomach than you have in your head!'"
