Phil, Alan, Stu, and Doug are back, and if the first official teaser trailer for "The Hangover Part III" is any indication, things haven't changed too much with the Wolfpack.

While the final installment of the popular series has abandoned the bachelor party and wedding premise of the first two films, the debauchery and high-stakes shenanigans on display in the new trailer promise that the booze-soaked, bad decision-based spirit of the original movies remains intact.

This time around, returning actors Bradley Cooper, Zach Galifianakis, Ed Helms, and Justin Bartha are joined by several new faces, including Melissa McCarthy, who shares a truly disturbing exchange of a lollipop with Galifianakis that reduces Helms's Stu to dry-heaving. John Goodman also makes his series debut, and franchise regulars Ken Jeong, Heather Graham, and Jamie Chung all reprise their roles.

The trailer closes with a simultaneously hilarious and horrifying gag involving Alan's new pet giraffe and a highway overpass, which certainly lives up to the clip's promise that the film is an "epic conclusion to the trilogy of mayhem and bad decisions." Here's hoping the rest of the movie follows suit.

"The Hangover Part III" hits theaters May 24.
