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.
