It's time to show off those silly walks and enjoy the sunny side of life, as the Mostly Python event returns to downtown Santa Rosa in front of Toad in the Hole Pub. Dress as your favorite character from the beloved British sketch show Monty Python's Flying Circus, and revel in the nonsensical troupe's best moments. Actors from Sixth Street Playhouse will recreate classic sketches live. This family-friendly event also features a crop of live music from North Bay Hootenanny staples the Crux, the Kyle Martin Band and others. It all happens Sunday, Sept. 21, at the Toad in the Hole Pub, 116 Fifth St., Santa Rosa. Free. Noon to 6pm. 707.544.8623.
