A strange thing happened when the cast of “Jersey Shore” arrived in Florence. Snooki, The Situation, and company – whose Italy-landing was covered on “Today” Monday morning by foreign correspondent Michelle Kosinski – are being tracked like mega celebrities by throngs of townsfolk. Although some onlookers voiced disgust for the cast (“They’re full of tattoo. They’re drunk. I think they are stupid”), the majority of locals seemed legitimately captivated by the guidos and guidettes.
