Break out your best viking get-up, or, conversely, your worst sweater and dingiest robe. Tonight, “Achievers” can relive the all the magic and all the sloth of the Coen brothers’ classic. The Big Lebowski (1998) has spawned countless weed-induced college-dorm revelations, a certain special strain of hipster fashion, and even an officially recognized religion (Dudeism, for disciples of The Church of the Latter Day Dude). And with more attendees than ever to Lebowski Fest, this internationally touring, 12-year-running “natural, zesty enterprise,” the Dude’s influence is better preserved than his rug. Dress up for tonight’s bowling party (past costumes have included bowling pins and a severed toe) and know your trivia to compete for prizes. Tomorrow, Cover Me Badd performs punk rock Lebowski covers before a screening of the film at Gramercy Theatre. As always, White Russians are the prevailing beverage of choice. At 8, Lucky Strike Lanes, 42nd Street and 12th Avenue, 502-583-9290, lebowskifest.com, $25–$30 HEATHER BAYSA
