"San Francisco librarian Dick Dillon is credited with the story" of the guy who had a tough day calling balls and strikes, hearing it from both sides, and catching not one but two foul balls off the shin, who gets home and, getting sassed by Junior on top of all that, finally blows up and gives out a good solid spanking.

Later, of course, he feels bad, and by way of apology, invites the youngster to come up on his lap and catch a little Baseball Tonight on the tube, together. The boy refuses. Why?

Because the son never sits on the brutish umpire.
