"Hi, my name is Zac"  and I have friends!  Seriously!  Look, here they are! Zac Efron seen here in Napa, California over the weekend looks like he’s about two seconds away from having that underwear pulled right over his head.  (And why exactly is he wearing a name tag? Is that some kooky thing the kids are doing these days?)   At least he’s got his good looks to save him.
