Its easy to enjoy watching Wit Tank when they are so clearly enjoying themselves, and their enthusiasm and commitment to their material is their greatest strength. This trio of up-and-coming young comedians inject their show full of energy and charm, wringing as much humour as possible from each line, and making one another corpse in a way that seems endearing rather than self-indulgent. Although the show takes a few sketches to hit its stride, once it does the laughs come thick and fast, with inspired characters such as the unhinged Uncle Party, a rousing series of after-dinner lectures by a brash explorer/bastard, and a delightfully thespian funeral director. The material is fresh and inventive, with clever set ups diverging in wonderfully absurdist directions, usually resulting in a brilliant and unexpected pay-off. Some material is weaker, with promising sketches occasionally left to trail off into unsatisfying punch-lines, or recurring scenes strung out a little further than they can support, but the trios impeccable comic timing and obvious camaraderie helps them carry off the more uneven sections. The group formed when they were students, and since graduation are trying their luck in the world of professional comedy, and they should go far with this smart, fun, and imaginative style of comedy, they are among the best sketch groups on the Fringe.
