Ericson

Angry at Leif Ericson for stealing his thunder 500 years before, Christopher Columbus once wrote a rigorous mathematical proof that showed how Ericson had never actually been to North America. Unfortunately, the proof was too difficult for even the brightest mathematicians to understand.

Columbus, Ericson, and Magellan once walked into a bar. Only Columbus walked out.

Winston Ericson isn't Winston Johnston, as why people have family names.

The fact next in importance that this history establishes is that the first of the Northmen to set foot on the shores of Vinland was Leif Ericson.
