Karl Hamilton, Kaci Scott, and Carl Hendin in Dirty Rotten ScoundrelsSome 20 minutes before the finale to the Timber Lake Playhouse's Dirty Rotten Scoundrels, you'll finally hear something that you hadn't heard once during the musical's first two hours: a legitimately sincere number. Granted, this romantic ballad is being sung by a practiced con man, and the object of his affection is a young woman from whom he's trying to swindle 50 grand, and he's only been hitting on her to prevent his rival from scoring first. But, hey, sincerity is sincerity, and besides, it's the only heartfelt moment you're gonna get.

Kyle Szen and Meredith Jones in The Wedding SingerOn Thursday night, the Timber Lake Playhouse opened The Wedding Singer, the musical-comedy version of 1998's love-in-the-'80s movie hit starring Adam Sandler and Drew Barrymore. Imaginatively and exuberantly directed by Brad Lyons, it's a joyful take on stage material that (in a wonderful surprise) is pretty damned terrific to start with, and Thursday's production was so big-hearted, so funny, so brilliantly costumed, and so smashingly well-performed that I might as well get it out of the way and say that its technical presentation was so routinely clunky that it bordered on the infuriating.

David Herr, Eli Pauley, and Phillip Newman in Lend Me a TenorThere are nights during the run of a happily manic, door-slamming farce when everything seems to go magically right: The actors hit their marks exactly on cue, the dialogue lands with almost inhuman accuracy, and the set's many doors open and shut with razor-sharp precision. The audience, meanwhile, barely has time in between laughs to catch its collective breath.

Kaci Scott and Thomas Stewart in GreaseI love TV's The Office for many reasons, but the most basic is that nowhere else on television will you find a weekly ensemble of 16 performers, each of whom is consistently in character, and each of whom is consistently funny. No matter where your eye lands in a group scene, you find yourself grinning - if not laughing out loud - at some priceless reading or reaction, and that's what routinely occurs throughout the Timber Lake Playhouse's current, knockout presentation of Grease, a production that, coincidentally, also boasts an ensemble of 16 stellar comedians. (Seventeen, if you count the hysterical, wordless, run-on cameo by Jake Bollman.) And Timber Lake's troupe even tops the sitcom's office drones in one regard, because damn, but this staff can sing.
