More than 200 shows. Seventeen days. And 20 venues. That’s SF Sketchfest 2017 by the numbers, and the artist lineup for the January festival is equally impressive and lengthy.

The performers, announced today, range from the casts of “King of the Hill” and “Kids in the Hall” to Megan Mullally to Ricky Jay. And the event isn’t without music, which includes a “Double Bill” combination of Grammy-winning guitarist Bill Frisell and Tony-winning comedian Bill Irwin. Jeff Goldblum and his band, The Mildred Snitzer Orchestra, will also return to the festival.

Tickets go on sale Sunday for the annual event, which will be held January 12-29 throughout San Francisco, and the full schedule is available today at sfsketchfest.com.

New this year is a benefit show featuring live music and scenes from a 1980s teen comedy, with proceeds going to 826 Valencia. The nonprofit, founded by writer Dave Eggers, offers free tutoring and writing tutoring to under-privileged students in San Francisco.

SF Sketchfest began in 2002 with six comedy groups in one venue.

Now, the event is a Bay Area fixture, with live podcasts as well as original audio shows from main sponsor Audible.

The event even has a full night of shows at the California Academy of Sciences. Among the night’s performers are original members of “Mystery Science Theater 3000” and Adam Savage of “Mythbusters,” according to the Academy’s website.
