The first full trailer for "The Hangover Part II" is here -- giving us a much clearer look at the kind of trouble the boys get into on their trip to Thailand!
Instead of tigers, babies and missing Doug, this time there's a wild monkey and a missing future brother-in-law, as Stu searches frantically for his bride-to-be's bro in Bangkok.
Bradley Cooper, Ed Helms, Zach Galifianakis, Justin Bartha and Ken Jeong all return for the flick, which opens Memorial Day.
