Which jokes are funny?

When two people were crossing the African desert in a hot air balloon, the balloon suddenly fell down. They jumped out of the balloon safely and walked in the desert for two days before they met the oasis.

The two men ran to the water source next to the oasis. There is a sign next to the water source, which reads: "Warning: drinking water will be executed! Chief word "

The two men have been thirsty for two days, and they fell down to drink water regardless of the willy-nilly. At this time, a group of natives suddenly appeared, tied them together and took them back to see the chief. The chief asked the two men, "I usually order you to cook and eat, but today is my birthday." If anyone can bring back a hundred fruits from outside, I will consider giving him a break. "

The two obeyed and took them out to find fruit.

The first man brought back a hundred wild cherries, and the chief ordered him to put them in his ass one by one and let him go without laughing. The man obediently stuffed wild cherries into his ass one by one.

He doesn't smile when he's stuffed for fifty and doesn't smile when he's stuffed for ninety.

By the 99th time, I suddenly fell on the ground and burst into laughter, even tears came out.

The chief was surprised and asked, "Why do you laugh when you have a cherry left?"

The man smiled and said, "Ha ha, look, my friend, ha ha. . . . . He brought back a hundred big watermelons. . . . Ha ha. . . . "
