As member of the undead in Twilight, Robert Pattinson spends his
fair share of time attempting not to bite people — specifically his
love interest, Bella (Kristen Stewart).

But it turns out Pattinson really got into biting guys on the set of the series’ second installment, New Moon.

Pattinson
told David Letterman, "There were a couple more guys on this sequel.
There was a guy, kind of, maybe a 230-pound guy who was at the
premiere, kind of Hispanic-looking, and he was asking me to bite him as
well. So I did. And surprisingly, I kind of liked it afterwards ... and
I've been out to dinner a couple times with him since."
