Lo-Ball! is a workshop to try out new material in the semifriendly confines of artsy-fartsy Ballard. Sure, the comics often have to compete with the World's Loudest Coffee Grinder, but Lo-Ball! is one of the few all-ages comedy shows in town (although NOT for children, unless you want them hearing about sex, abortions, and robots who have sex and then abortions). (Mr. Spots Chai House, 5463 Leary Ave NW, 297-2424. 9 pm, free, all ages.)
