Rick Reilly Just Compared Martin Kaymer to Nazi Germany on Twitter

Rick Reilly recently retired from sports writing with great fanfare. But if you think that’s going to keep him from delivering knee-slappers, you’re sorely mistaken.

Check out this gem from the columnist following Martin Kaymer’s hot round at the U.S. Open.

Allow us to show his work: Kaymer, you see, is German. A Nazi Germany easily conquered Poland in 1939.The joke practically writes itself.

Some people, as you might imagine, aren’t too happy with this tweet. Diving into his replies is like sticking your knob in a hornet’s nest. Risky, risky stuff.
