Having a blue Christmas season so far? What you need are some laughs.

A good place to find them is the 6th Street Improv troupe’s “Holidaze” comedy show at 8 p.m. Sunday, Dec. 16, at the 6th Street Playhouse, 52 West 6th St., Santa Rosa.

“We’ll have elf experts, mystery gifts, impromptu holiday songs and even a little improvised Dickens,” said Bridget Palmer, the show’s producer.

Tickets: $10-$14.
