(Online story updated with more open mics.)

Go to one of D.C.’s many free open mic comedy nights, and you’re likely to get more than you paid for. Mixed in among the retrograde groaners are absurdist flights of fancy, thoughtful social commentary and bon mots worthy of their own Comedy Central specials. Not enjoying yourself? Take a trip to the bar or bathroom, and a new comic will have the mic by the time you return.

Mondays

The Big Hunt, 1345 Connecticut Ave. NW; 8 p.m. This open mic is hosted by David Tveite, a self-deprecating Midwesterner with a knack for observational comedy.

Jake’s American Grille, 5018 Connecticut Ave. NW; 8 p.m. Hosts Matt Dundas and Chris Blackwood have been known to pit audiences against comedians in topical joke contests.

The Salty Dog Tavern, 1723 Connecticut Ave. NW; 8 p.m. In addition to a solid cast of local comics, there’s also surprisingly tasty food at this basement bar.

Black Whiskey, 1410 14th St. NW; 8 p.m. The rare open mic with an actual stage, this popular show is hosted by local comedians Chris Brandt and Max Wolfson.

Thursdays

The Bier Baron Tavern; 8 p.m. Host Bill Metzger keeps the evening pleasantly weird at this weekly comedy show.

RFD, 810 Seventh St. NW; 8:30 p.m. Comics love this long-running open mic because it has its own dedicated room, which means they aren’t ambushing unsuspecting bar-goers with unwanted jokes.

The Science Club, 1136 19th St. NW; 8:30 p.m. Tip back a beaker of vodka while David Coulter and Max Rosenblum host an evening of laughs that are, unfortunately, not science-themed.

Topaz, 1733 N St. NW; 8 p.m. This intimate room holds only about 45 people, so get there early to grab a seat. Then use that time to think up a joke — the audience member with the best one wins $25 at the end of the show.
