Zach Galifianakis has let slip that the plot for "The Hangover Part III" in his Rolling Stone interview.

Zach Galifianakis covers the recent issue of Rolling Stone magazine where he revealed some of the highlights in the next possible sequel of the highly-successful low-budgeted film “The Hangover”.

To quote:

That doesn’t mean he’s going to stop making movies. “They want to do a Hangover III,” he says. “I’m getting fricking phone calls already.” According to what he’s heard, the plot ditches the format of the first two and focuses on his character escaping from a mental institution with help from the wolf pack.
