Not as cool as the conversation you had, but when I was in college I worked at the golf course. Billy Stacy (3rd overall pick in the NFL draft for you youngsters who don't know him). He would pick me up a lot of days and get me out of the pro shop, and we'd ride around and "refill water coolers."

He told me the story of Jim Brown ending his NFL career with a knee to the cheek, stated Jim Brown was the only football player that every scared him, said it felt like he was tackling a truck. I never forgot that conversation.
