The team I worked on tried to introduce Scrum. The main problem was that the guy who got appointed as Scrum leader (coordinator - head honcho or whatever) never turned up much before midday and the daily meetings were held at 09:00. So the guy who was supposed to be hosting them was never there!
He should have been fired for abysmal timekeeping but that didn't actually happen until 2 years later when the management finally realised he wasn't actually doing the hours he was claiming!
