Nephews Say the Darnedest Things, Part 2

During my recent trip to Austin, I was watching a Rangers game on TV with my youngest nephew, who has recently started playing Little League himself. When Rangers manager Ron Washington went out to change pitchers, the name on the back of his jersey was quite visible...

NEPHEW: His last name is Washington?
ME: That's right.
NEPHEW: He must be George Washington's son.

(I reminded him that George lived in the 1700s and Ron was in his early 60s, so they probably couldn't be father and son.)
