Mine rocks out with his cock out. I get a little annoyed with him constantly pressing us to find better ways of working, when we're already the #1 team.
But still, the man really knows his shit and has turned a lot of things around for the company. He's a good person to approach when you're having a problem, of just about any sort.
OTOH, before we had him, we were floundering around trying to play agile and not actually accomplishing anything.
Never met a scrum master yet who was actually a driven motivated individual. Its almost like it's a default job you just fall into if there's nothing else for you
I've seen at least two SMs who were really motivated and they can actually be a tremendous help.
My last project was complete chaos, and that one lone SM managed to get it all streamlined and efficient. Then he was pulled from the project and everything collapsed again.
