I also think they do work hard. There are some results to show for it. However effort is not the same as result - the transmission belt between the two is the management, so it may go well or not work at all.
Ole and Sven were two men courting Lena, a young widow with a large farm. One sunny morning, she called them both into her kitchen. She explained, "Now I like you both, you're both very sweet, but I can only marry one of you. What I really need is someone to help me run this farm. Now then, my cows have been getting into my north field, so I need it fenced off. Ole, I want you to take east side, and Sven you take the west. Whoever plants the most fence posts by the time I bring you both lunch, I'll marry."
Lena watched the two men for a while through her kitchen window. Sven immediately grabbed a shovel, and started digging with gusto. Great clods of sod and dirt flew into the air as the man went to work. Ole, on the other hand, just leaned against the southern fence, staring at the stack of fence posts on his side. Shaking her head, Lena turned her attention to preparing lunch for the three of them.
Three hours later, she packed a basket, and walked to the north field, wondering what, exactly, had happened. On the east side, Ole had not only finished planting his fence posts, but had also taken the slats from her barn, and was currently filling out her new fence. To the west, however, no fence posts were to be seen. Only a long line of dirt mounds revealed that Sven had done any work at all.
Puzzled, Lena approached Sven, and asked, "Sven? What happened? You were working so hard!"
"Well, that Ole, he cheated..." Sven explained. "He left half the posts sticking up!"
