Back in the original Zul gurub one of our Druid healers went moonkin as it was the new thing at the time. He was playing with skull piles and got mind controlled. Never in our guild's history, then or since, has everyone perfectly fixated on something attackable and obliterated it. I still get a smile thinking about how fast poor Vega got lit up by the rest of the raid, and fell over dead. Good times!
