Probably heard it before. 3 guys get stranded on an island.

A black guy, a white guy and a Spaniard are on a boat. The boat hit a rock and sinks, so the three men swim to the nearest island. When they get to the island, they're greeted by the natives that live there. When confronted the men ask if they can stay on the island until they're rescued. So the natives group up and discuss. After a few minutes of discussion the chief of the natives comes over and tells the men they can stay on one condition. He says "each of you must go into the forest, find 2 fruits each and bring them back to the beach". Simple enough. The men go into the forest and split up.. the black guy is the first to come back. He has a grape and a banana. The chief then tells him the second condition. "You must now shove each of the fruits up your ass with it making a sound or we'll cut off your head". Grudgingly, the black guy shoves the grape up and starts laughing. They cut off his head and goes to heaven. The white guy is the next to return. He has a strawberry and a banana. After being told the second part, he gets the strawberry, up and the banana half way before he starts laughing. They cut off his head and he goes up to heaven. While waiting to get into heaven the white guy asks the black guy what happened to him. "He says the grape popped and it tickled, what about you? " the white guy responds
"I saw the spaniard coming back with a pineapple and a watermelon"
