2 financial market theorists were walking down the a busy street. The 1st pointed out a $100 USD bill on the sidewalk. The 2nd commented that this could not be possible, surely if it was a $100 USD bill someone would have picked it up by now. The 1st agreed, there is no way that there could really be money on the sidewalk of such a busy street. So without picking up the money or investigating further, they proceeded on their way.

Not really funny, just a dig I guess

I prefer the one that says if u have enough economists standing in a row to go all the way around the world they still wouldnt reach a conclusion.
