John Pinette, the Kirby-shaped ex-accountant from Boston, has carved out a niche in the comedy world as an oral documentarian of the obese man in search of a faster fast-food line, an easier workout, and a more hospitable water slide. While many comics rely on dissecting relatable events and finding common ground with their audiences, Pinette’s act largely relies on the fact that he is different: His material tends toward embellished tales of the many instances in which his corpulent frame and excessive appetites have run up against the unaccommodating infrastructure of society. And though Pinette is in many ways a caricature of the loud, fat, unrepentant American male, this is not to say he is culturally narrow: He also does accents—specifically, the Chinese restaurateur who bars him from the all-you-can-eat buffet, the French concierge who pretends not to speak English to avoid telling him where the complimentary breakfast is being served, and the Japanese tourists who, at the water park, mistake him for the whale from Free Willy.

JOHN PINETTE PERFORMS AT 8 P.M. AND 10:30 P.M. AT THE DC IMPROV, 1140 CONNECTICUT AVE. NW $22. (202) 296-7008.
