• The Sound of Young America Live: Live public radio featuring Jesse Thorn, Morgan Murphy, Merlin Mann, Danny Hoch, and Bucky Sinister perform le stand-up hot. Zach Rogue (of Rogue Wave) provides the music. It's indie rock and comedy all rolled into one. Ta-da! Oh, and it's part of SF Sketchfest, so you know it's good. Show starts at 8 p.m. at the Eureka Theatre; $10.
• BiFriendly Social: A bisexual coffee klatch for men and women who lean on both sides of the fence. (No, not for you alterafag Manhunter subscribers who claim bisexuality only in effort to entice seemingly straight men, but for authentic bi guys. Wherever they may be.) No set topic, just an old-fashion chat with strangers all juiced up on caffeine. Or whatever. Anyway, it goes from 7:30 p.m.- 10 p.m. at Church Street Cafe (formerly Muddy Waters); free.
• Tonight's Macworld Expo Afterparties: Leave the goatees in the bathroom sink. Please.
• Bart Davenport: Dreamy Berkeley pop-rock and folk star, and sometimes Honeycut frontman, performs for his mass of swooning fans. Check him out tonight, and then you can say you're one of them. He goes on at 9:30 p.m.. at Cafe du Nord; $5.
