Most often question: Why is the observer's seat inverted?
But by far the dumbest one I had was last summer:
I had a friend preparing for a pass when this guy comes in our way waving and screaming at us on his seadoo...I sunk my skier and stopped (swearing) and asked the guy if he was in any trouble...
He said: ''Man be carefull overthere! It's pretty shallow...didn't you see all the red and yellow warning buoys????
I have to admit, at that very moment, just for an instant, I thought of ending his pain and suffering.... But instead we went off laughing...(of course we invited him to stay there and observe for a few minutes).
