Paul Reiser loves a good laugh. Starting out in standup, Reiser later moved on to film and television, known best for his roles in My Two Dads and Mad About You. Reiser has also written books and songs—he’s the guy you can thank for having the infinitely catchy Mad About You theme song stuck in your head for five years—but when it comes down to it, out of all of Reiser’s projects, standup comedy is still where he most excels. Hear his sidesplitting humor on Saturday, Mar. 23. Napa Valley Opera House. 1030 Main St., Napa. 8pm. $30—$35. 707.226.7372.
