Join us every Saturday as we add up the week’s stories about the Sistine Chapel and divide them by the number of angry commenters who realized that Christmas light displays actually should be protected by the First Amendment, in retrospect.

— In retrospect, if the Vatican didn’t want to attract all those dirty tourists it’s now going to have to vacuum before they enter the Sistine Chapel, they should have done more to put an end to decades of papal abuses.

— In retrospect, there can never be too many artists’ projects on gun violence and gun control — until tragedies like this month’s school shooting in Connecticut cease to be regular occurrences.

— In retrospect, Cai Guo-Qiang’s exploding Christmas tree outside the Smithsonian’s Freer and Sackler Galleries may have been as out of step with the yuletide spirit as Sarah Childs’s “obscene” Christmas light display, but both are equally deserving of protection under the First Amendment.

— In retrospect, Thomas Kinkade’s widow and girlfriend probably reached their secret court settlement when they simultaneously realized they didn’t want to be the public spokesperson for the late “Painter of Light” for the rest of their lives.

— In retrospect, we could’ve written 20 much funnier headlines about the National Museum of Mathematics’s opening, but instead we chose to trash five other news outlets’ attempts.
