Zac Efron, who hasn't been hanging out shirtless at the beach NEARLY as much as I was hoping he'd do this Summer, surfaced this weekend in New Orlenas, LA lookin' about as Summery as possible in his colorful boardshorts, tank top and ... knit cap? Well, OK, in this blistering heat the knit cap looks silly but ... if you focus on his toned arms, you don't even notice the hat at all.
