In the mid-’90s, you couldn’t escape comedian Paul Reiser. His sitcom Mad About You, which detailed the woes of commitment and marriage, drew millions of viewers every week, and his face appeared on the covers of his bestselling books Couplehood and Babyhood. Though he’s not as ubiquitous as he was two decades ago, Reiser continues to appear in select works, including Behind the Candelabra and Curb Your Enthusiasm, causing audiences to remark, “Hey, I always liked that guy.” Because everything old is apparently new again, Reiser is returning to his stand-up roots and performing shows around the nation. Signature Theatre even adapted Reiser’s breakout role in Diner into a new musical last winter. While his material may have matured (the babies he once wrote about are now young adults and you know he has feelings about that), the nice guy image he’s cultivated remains largely in tact. A Mad About You reunion about neurotic New York grandparents is surely imminent. Paul Reiser performs at 8 p.m. at the Howard Theatre, 620 T St. NW. $35–$45. (202) 803-2899. thehowardtheatre.com.
