Three guys get captured by natives on an island... They are brought up to the top of a hill in front of the chief of the natives where he makes them an offer. ""If you can shove 10 of any fruit you find on the island up your butt and keep them there, then you will be released. Otherwise, you must stay here as slaves."" So the first guy goes to the bottom of the hill and looks around and finds strawberries. He starts shoving them up, but can only get to five before he gives up. The second is a little smarter and finds blueberries. He too begins and is looking very impressive. However, when he gets 9 he starts laughing and all of the blueberries fall out. The first man approaches him, ""Hey what happened? It looked like you were going to do it."" ""Yeah I was going to, but then I saw the third guy running up the hill with pineapples.""
