It seems to me that humour is everybody's way of keeping sane and standing off from the situations so that they can see it intellectually, as well as emotionally, and I don't know whether you've noticed, but if somebody tells a joke, it's nearly always a mini fantasy.
I learned from different guys I played with, too. The key was probably three people: The good Lord, the offensive linemen I played with and great fullbacks that could block very well.
