The German finance minister Wolfgang Schäuble hasn’t been the jolliest fellow since this whole Greek thing started heating up. 

But he made kind of a debt crisis “funny” this afternoon.

In a speech today, Schäuble said, “I offered my friend (U.S. Treasury secretary) Jack Lew these days that we could take Puerto Rico into the eurozone if the U.S. were willing to take Greece into the dollar union. 

He thought that was a joke.”
