There is a joke that includes Liu Bei, watermelon, grapes, Zhang Fei and Guan Yu.

It is said that Liu's three brothers drifted to an island and were caught by local tribes. The chief said to them, You three go to the forest over there and each of you will pick a fruit. If I am satisfied, I won't kill you. Liu Sanren went. Zhang Fei came out first and took an apple. The chief said, OK, then you put the apple in your anus. If you can't put it in, I'll kill you. Zhang Fei wasted a lot of energy and was killed without stuffing it. Then Guan Yu came out and took a grape. The chief said: Yes. Then you put the grapes in your anus, don't break them, and keep them for ten seconds. Guan Yu stuffed grapes into his anus and they were fine for the first nine seconds. As a result, in the tenth second, Guan Yu turned around and smiled, smashing the grapes. As a result, Guan Yu was also killed by the officer. When I got to heaven, God asked Guan Yu: What's the matter with you? One more second and you won't have to die. Guan Yu said that there is no way. I saw big brother take out a durian.
