Preshow snow and steaming cups of spiced apple cider in the lobby are only the beginning of the frivolous fun at the 12th annual production of this gleefully goofy holiday comedy. The brainchild of brothers Shaun and Brandon Loeser, this all-guy sketch show includes a send-up of the three wise men, a screaming family's Christmas dinner and a priceless striptease by the unabashed cast. Riffs on an Eminem rap and a Mafioso-style Santa-run operation are only a few of the repeats from past shows, but the intensely silly material never gets old. Interspersed with the staged shenanigans are short films — Brokeback Igloo, Pirates of the Caribbean: On Santasia Tides and Pulp Christmas, to name a few — that add hilarious yuletide twists to a few Hollywood blockbusters and feature some classic claymation. Monologues summarizing each cast member's favorite Christmas memory add a sweet touch to the lunacy, as does a collection of onstage, fully lighted Christmas trees and a house aglow with kitschy lights and real-life Loeser family memories.
