The Traveling Salesmen and the Farmer's Daughter

(Obligatory traveling salesmen break down, ask farmer for shelter, farmer warns against sleeping with daughter, salesmen do anyway setup...)

"As punishment," the farmer says sternly, "you're going to help me with my harvest. Go outside and pick one hundred of your favorite fruit."

The salesmen looked at each other. Despite the menacing look of the farmer holding a shotgun in their faces, they both breathed a sigh of relief.

"Just one hundred of our favorite fruit, and we can go?" one salesman asked.

"Yes," the farmer said, matter-of-factly.

The two salesmen embark into the fields, and one returns almost promptly,l holding one hundred cherries. The farmer menacingly holds the shotgun in the salesman's face, and says, "Now, if you want to get out of here alive, stuff all one hundred of those cherries up your ass."

"Are you serious?" the salesman exclaimed.

The farmer held up the shotgun, as if to nonverbally declare his seriousness.

The salesman dropped his pants. He managed to get 25 cherries in his ass, but then he blurted out laughing, as if out of nowhere, and the cherries shot out. He managed 50 cherries, but through his hearty belly laughs, they shot out. The salesman made it to 75 cherries, but laughed so uproariously that they shot out with vigor. Finally, the salesman was able to fit all 100 cherries up his ass, finally ending with one of the loudest laughs the farmer had ever seen.

"OK, son, you can go," said the farmer, "but before you do, tell me what in the blue hell was so funny?"

The salesman's reply? "My coworker's out there picking watermelons."
