I have a few choice morsels fired my way when I was the only guy that used to kite one beach in the US when I lived there. The two top ones would have to be:
1)When I was packing up (wearing a full steamer at the time) I got asked by one woman "Did you just parachute in?"

WTF? "Um no, it's a kite".
2) Old bloke walks up not overly impressed and says "Yeah, I used to have one of them attached to my boat"......... Somehow I don't think so tiger
