What do you want for your last meal on earth? Jimi Hendrix had a tuna fish sandwich, Timothy McVeigh went with mint-chocolate-chip ice cream, Julia Child ate, fittingly, a bowl of French onion soup. So: what are you having?

“At first, spending 24 hours without cell phones or internet felt like a feat of endurance, like a marathon. We didn’t enjoy it, but every week we did it and every week we congratulated ourselves on having dragged ourselves across the finish line. But after a month or so we realized that the performance of a stunt, over and over again, was going to get old quick. That’s when we started lighting candles on Friday night: to try to make it, rather than a deprivation, a gift to ourselves. We haven’t always succeeded, but in its best incarnations the UNDO day has been a great date – an adventure through the city, or else a quiet day in bed snuggling and watching “The Wire” (Yes, we allow ourselves movies and television as long as we’re watching together. And yes, we only just started watching “The Wire.” Shut Up!). The break has become something we look forward to rather than endure.” (Sara Hess)

It’s a good day to head up to the Skirball, which has two amazing exhibits going right now, both dealing with the real-life cultural experience of Jews (who are, after all, pretty much the OGs of this undo day mishigas). Jewish Homegrown History is a home movie art installation where you can choose, via touch-screen, from a huge library of unedited home movies depicting weddings, haircuts, vacations and other intimate moments.The second, Project Mah Jongg, is devoted to the tile game beloved by old ladies and hipsters and its cross-cultural relationships between American Jews and Chinese Americans. $10 admission.
