The Walnut Room is best known as a place to catch hip bands, listen to spoken-word artists at the monthly Cafe Nuba events and preview movies made by local filmmakers. On Sunday nights, regulars gather around the bar to catch stars of a different sort. Do the names Moe Szyslak and Abu Nahasapeemapetilon ring a bell? How about Dale Gribble, Boomhauer and Stan and Hayley Smith? If so, you'll fit right in when the bartender turns on the TV for a Fox lineup that includes The Simpsons, King of the Hill, American Dad and/or Family Guy. (Save your serious drinking for the half-hour when the godawful sitcom The War at Home comes on.) Just what was it that Ralph Wiggum found up his nose? Can Hank learn to embrace Bobby's feminine side? What Hollywood star does Roger the alien have a crush on now? Stay tuned.
