Then economist 1 kicks economists 2 in the balls and gives him $100.

They continue walking and see a big pile of shit.

Economist 2 says to economist 1: I’ll give you $100 if you eat that pile of shit.

Economist 1 says “sure”, eats the pile of shit and economists 2 gives economists 1 his $100 back.

They continue walking, eventually economist 2 asks “What was the point of what we just did?”

Economist 1 responds “We just increased GDP by $200.”
