Three Americans (Bill, Bob, and Jimmy) took a trip to South America and are walking along the Amazon river banks. Suddenly, they're ambushed by a tribe of cannibals. The cannibals told the three guys that in order to live, they must pass a trial. The first part of this test was easy. Go out and collect 10 pieces of one kind of fruit.
Bill comes back with 10 apples. The tribe leader then said, "For the next part of the test, you must place each one of these apples into your rectum without making a face or a sound of any kind." The guy got the first two in fine, but then on the 3rd he winced in pain. The tribal leader condemned him to death.
Bob came back with 10 cherries. He got 8 of them in, and then started laughing for some strange reason. The tribal leader condemned him to death as well.
"How come you started laughing?" asked Bill.
"I spotted Jimmy coming back with 10 pineapples."
