Find a joke! ! ! ! ! ! !

Two economists are walking in the park.

When I was walking ... I suddenly found a piece of shit on the road.

My brother said to my brother, I'll give you 50 million yuan if you eat shit! After calculation, my younger brother thinks that it is quite cost-effective to eat 50 million pieces of shit. So the deal was reached, and the senior gave his brother a check for 50 million.

Keep walking and find another lump.

The younger brother smacked his lips, thinking that the smell of shit was really unpleasant, he said to his younger brother, I'll give you 50 million if you dare to eat it. The big brother is distressed by his 50 million. Seeing his brother say this, he ate clean for a while. So the weight of 50 million returned to my brother's wallet.

Go on, brothers and sisters hugged each other and cried: I didn't earn a penny, but I ate a lump by myself. ...

Back in front of the master, the old professor trembled with excitement: 100 million, 100 million! You two have added 100 million GDP to the country without doing anything!
