Whoever tells a funny joke will be awarded points based on the level of the joke.

Once upon a time, Americans visited Russia. One day I saw two Russian workers on the road in Russia. One was digging holes beside the road with a shovel, and he was digging a hole every three meters. The other worker was immediately backfilling the hole that the previous worker had just dug. The Americans were curious and asked the first Russian worker: "Why did the man behind you fill the hole as soon as you dug it?" Get up? ”

The Russian worker replied: “We are greening the road. I dig holes, the second person plants trees, and the third person fills the soil. But the second person asked for leave today and didn't come. 』
