St Bartholomew suffered martyrdom after he had been flayed - skinned alive. Some sources claim he was then crucified, others that he was beheaded. In memory of the flaying, some Italians include dishes made from wide, flat pasta, such as taglierini, as part of their feast day specialties.
BTW - if you have weight problems - Bartholomew is the saint to go to for shedding pounds - or putting weight on. He's worked miracles associated with weighing things...
Bonus question: If they flay you, are you still naked? Is that good or bad nudity? What?
