The first 'Hangover' made Bradley Cooper, Ed Helms, and especially Zach Galifianakis stars, and it elevated Todd Phillips from middling Hollywood director to name-brand comic auteur. But in the film industry, success that surprising and enormous demands more success; the beast must be fed. But as 'The Hangover Part II' and especially the new 'Hangover Part III' prove, it is very hard to make a good sequel to a truly original idea. 'Part II' went the rehash route, recycling the plot of the first movie so brazenly you almost had to admire its chutzpah. 'Part III' finally breaks with the formula a little (SPOILER ALERT: there is no hangover), but still doesn't produce anything even remotely worthy of the first film.

This week, 'Funny or Die' co-founder Will Ferrell finally sat down between the the two potted plants and, naturally, things got a little weird.

In this case, Phil (Bradley Cooper), Alan (Zach Galifianakis) and the gang travel to Thailand to celebrate Stu's (Ed Helms) upcoming nuptials. While there, they decide to go on another bender, only to wake up with face tattoos, shaved heads, a monkey -- everything but Stu's fiancee's little brother, Teddy, who has gone missing. From there, they must retrace their spotty steps and find Teddy before it's too late.
