At least audiences get a fresh premise: Phil (Bradley Cooper), Stu (Ed Helms) and Alan (Zach Galifianakis) must track down crackpot on-the-lam thief Mr. Chow (Ken Jeong) and deliver him to John Goodman's drug goon. (Or, as Chow refers to him twice, "a fat f--k.")
The dudes trek from Tijuana, Mexico, to Las Vegas, to carry just a few jokes in their baggage. The bulk of them belong to the surreally odd Galifianakis, who even milks hilarity out of licking a lollipop. Cooper and Helms, meanwhile, are underutilized as exasperated straight men.
Somewhere between Phil shimmying down the front of Caesars Palace and Mr. Chow on all fours eating dog food, it becomes clear how far the franchise has fallen.
