JOKE: Raila, Moi and Kibaki Ordered To Bring a Fruit

This is an old joke, but still cracks me up.
Raila, Moi & Kibaki were lost in the forest and were captured by cannibals. The cannibal king told the prisoners that they could live if they pass a trial. The first step of the trial was to go to the forest and get ten pieces of the same kind of fruit.So all three men went separate ways to gather fruits.
Moi came back and said to the king,”I brought ten Oranges.” The king then explained the trial to him. “You have to shove the 10 fruits up your butt without any expression on your face or you will be eaten.”
The first orange went in…. but on the second one he Cried out in pain, so he was killed.
Raila arrived and showed the king ten berries. When the king explained the trial to him, he thought to himself that this should be easy.1…2…3…4…5…6…7….8…9 and on the tenth berry he burst out in laughter and was killed..
Moi and Raila met in heaven and moi asked Raila , “Why did you laugh, you almost got away with it?”
Raila replied, ” I couldn’t help it, I saw Kibaki coming with Watermelons
