BYRD, ANTARCTICA—Brad Swithers, three-time winner of the Molson Ice/Edge Gel South Pole Laff-Off, said Monday that he is running out of ideas for observational humor about life in Antarctica. "I've already made tons of 'What's the deal with those ice chunks that form between the huskies' toes?' jokes," Swithers said. "And, of course, I've done the whole penguins-and-smelt thing to death." Swithers added that he's currently working on a bit about the differences between Amundsen Bay and Voyeykov Ice Shelf women.
