Hey trivia fans, if you’re up tomorrow morning, be sure to tune into National Public Radio’s “Wait, Wait, Don’t Tell Me” between 11 a.m. and noon (on 88.5/WAMU) because a DCist contributor (not your editor) will be on the air lending his authority on a certain subject to confuse the hell out of an unlucky contestant. We don’t want to ruin the surprise, but it may or may not involve something in a triangular-shaped park across the street from a mansion-turned-historical society-turned-museum designed in a form of beerhouse baronial architecture where — in a piece of personal trivia — this DCist’s great-great grandfather did all the ornate woodcarving.

UPDATE, Saturday, 11:45 a.m.: Ding, ding, ding. If you didn’t catch the program, three news items — two fake, one real — were read by the likes of Mo Rocca and the Post Style section’s Roxanne Roberts to a contestant from St. Paul, Minn. One story involved a giant memorial to a roll of Charmin toilet paper, another about Bono of U2 fame getting pissed off about someone trying to capitalize on his image by baking it into loaves of bread and the third involving a memorial to another Bono, this one the late congressman from Palm Springs, Sonny Bono.

Any reader of DCist can quickly recognize the real news item, the one of Sonny Bono Memorial Park near Dupont Circle, something DCist contributor William Beutler wrote about for our obscure monuments feature, which eventually turned into an article he wrote for The Washington Monthly. The article is only in the print edition, so go pick it up, or read his in-depth post on the park here.
