The few times I've seen him in person he has always seemed like a pleasant, good natured man with a bad temper (I have no problems with people with bad tempers). Although this past June at the hall of fame induction weekend Lou needed more help than usual to get around. He needed a cane and the help of his daughter to get around. He was still in good spirits though, despite the cold, rainy weather.
My favorite Lou Duva moment, hands down, was during the Holmes-Holyfield fight. Lou kept yelling at Holmes for staying in Holyfield's corner during the fight, and when the bell ended (can't remember which) the round, Holmes just smiled and ruffled up Duva's hair, which pissed him off more than you can imagine. HAHA. Classic moment in boxing history.
