Welcome to McSwiggins. For the motley assortment of career barflies, neighborhood hotheads, Walmart Casanovas and lovelorn alcoholics who make it their home away from home, the old-school Hollywood watering hole is the kind of place where everybody knows your name (or soon will, though you’ll probably regret it long before last call). Playwright Lance Whinery’s irresistibly goofy, one-act parody of the hallowed saloon sitcom takes the form into the kind of seedy, low-rent dramatic neighborhood where the denizens of Cheers were never drunk enough to tread. Its intentionally insipid plot, cliché-ridden characters and wincingly corny one-liners are frighteningly familiar. And in Thomas Blake’s environmental staging, where the audience has ostensibly joined the regulars to toast the beloved bar’s final night in business, the manner in which the actors shamelessly cheat their punch lines toward the spectators creates the impression of being a captive member of a live TV-studio audience. Then the other shoe drops: As the story and the drinking progress, and the characters’ alcohol-fueled belligerence morphs into an increasingly maudlin and effusive bonhomie, Blake unleashes his cast of expert ad libbers and insult comics (standouts include David Alfano, Tobias Jelinek and Kim Estes) into the audience to harass and humiliate. But there won’t be any hard feelings — because in true sitcom logic any conflicts that erupt or are miraculously resolved will be mercifully nullified in the amnesiac haze of the morning’s hangover.
