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."

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."

The act of biting isn't as simple as it seems, Pattinson told Letterman. The prudent vampire always uses a bit of forethought and planning before breaking out their fangs. "It depends on your mood really," Pattinson said. "And it depends what you want to get out of it at the end."

On his relationship with 'New Moon' co-star Kristen Stewart, Pattinson was tight-lipped. "I've been ... cryptically avoiding this question throughout the entire press tour," he said. Letterman wasn't content to let Pattinson get away with a noncommittal answer, however. Check out his retort in this clip.
