How does Robert Pattinson deal with rabid 'Twilight' fans? Why, he bites them, of course, regardless of their gender.

Last night, Pattinson told David Letterman the story of how one fan, a man he described as tipping the scales at more than 200 pounds, asked to receive a bite from everyone's favorite vampire. Pattinson jokingly said he was happy to oblige. "The surprising thing was I kind of liked it afterwards," he said. "I've been out to dinner with him a couple of times."
