He could chuck a peck of pickled peppers.
A traditional, if nonsensical, "response" to the question is: "A woodchuck would chuck as much wood as a woodchuck could chuck if a woodchuck could chuck wood"
A 1957 Associated Press piece refers to the question as "a riddle which beats the Sphinx, since it's still unanswered".[6] A more concrete answer was published by the Associated Press in 1988, which reported that a New York fish and wildlife technician named Richard Thomas had calculated the volume of dirt in a typical 25–30-foot (7.6–9.1 m) long woodchuck burrow, and had determined that if the woodchuck had moved an equivalent volume of wood, it could move "about 700 pounds (320 kg) on a good day, with the wind at his back".[7] Another study, which considered "chuck" to be the opposite of upchucking, determined that a woodchuck could ingest 361.9237001 cubic centimetres (22.08593926 cu in) of wood per day.
Even Wikipedia doesn't have a definite answer ! LOL Hope you're not bored any more !
