PREVIEW Leap year is here! Looking for a suitably unusual event to celebrate this once-every-four-years occurrence? I strongly suggest scampering over to the Hemlock Tavern for a Club Chuckles lineup that’s poised to scramble the brain of any comedy connoisseur. Headliners Borts Minorts defy simple description. See, there’s this guy in a hooded white unitard and a headset mic who sings and flails and contorts — he might be an alien or an android, but it’s doubtful anything but an actual human would be able to bring such pure and bizarre joy to the stage. Equally enthusiastic are the Borts backup dancers, who flaunt leotards and fishnets (and the occasional pair of lederhosen), and whose energetic choreography demonstrates limber limbs and an admirable appreciation of jazz hands. Borts’s music is similarly befuddling, in the best possible way — a combination of samples, keyboards, horns, drums, theremin, slide whistles, a single-stringed bass made out of a snow ski, and god knows what else, but I guarantee you’ll not see anything as sense-assaultingly entertaining this leap year, or any other year. Local duo Ramshackle Romeos render classics like "Feelings" with nearly as many instruments as a full orchestra (including a mean musical saw), and comedians Drennon Davis and Alex Koll rock the mic between musical numbers.
BORTS MINORTS With Drennon Davis, Alex Koll, and Ramshackle Romeos. Fri/29, 9:30 p.m., $8. Hemlock Tavern, 1131 Polk, SF. (415) 923-0923, www.hemlocktavern.com
