The first poster for Sony's comedy sequel Grown Ups 2 proves that summer isn't just for kids. Adam Sandler returns as Lenny Francis, who moves his family back to his hometown. Instead of the grown ups teaching their kids a thing or two, it's the adults who learn a lot from their children on a chaotic last day of school. Take a look at this poster featuring Adam Sandler, Kevin James, Chris Rock, and David Spade cutting loose and having a good time.
