Wednesday’s column is about the Rancho Cucamonga Public Library’s telethon from last weekend, an unusual amateur-entertainment extravaganza, televised on the local cable channel, that raises money for the library. I was recruited for the Trivia Challenge, not as a contestant but as a judge.

Above, Robert Karatsu, the library director and trivia master, examines the answers to one question, as do I. (Answers were multiple choice.)

One question, below, involved my hometown. If you don’t know the answer, it’s in my column.
