Jokes on a desert island

I know a similar joke. Americans, Germans and Japanese were shipwrecked on a desert island. I didn't expect there were cannibals on the island and I was caught. The chief told them to look for ten round things on the island, or they would eat him. Then Americans found ten longan and Germans found ten peaches. The chief told them to swallow everything they found in ten minutes, or they would eat him. Americans ate ten longan easily, while Germans ate five peaches, and they couldn't eat any more. As a result, they suddenly laughed with peaches until their mouths cracked. The director asked me strangely, this is playing a trick on you, why are you still laughing? The German said, just now, when I was looking for peaches, I saw the Japanese climb the tree to look for coconuts.
