Is it just me or do you never want to go on vacation with these boys?

If you though their Las Vegas trip went a bit awry then wait to see the trailer for “The Hangover Part II."

The 2009 buddy comedy starring Ed Helms, Bradley Cooper, Zach Galifianakis and of course, who could forget, Mike Tyson, launched these comedic actors into stardom and the next instalment looks like it’s going to live up to the original.

The Wolf Pack is back. The movie seems to start in the same vein. The group of friends organize a bachelor night out and wake up with a wild animal, without a friend and no recollection of the previous evening. Except this time they’re in Bangkok, Thailand and Helms has a tattoo on his face.

Some of the original players from the first movie also make an appearance including Justin Barth (the only sensible friend in the group, Doug) and Ken Jeong as Mr. Chow. Ireland’s own Liam Neeson will also make a cameo in the movie as the Tattoo guy and Mike Tyson is also set to drop in.Neeson said that filming the movie was intense.

In February, Galifianakis said he loved filming in Thailand. Speaking to ET, he said “I don't really want to go back because I find that I might be bored when I go back to the United States. This is, like, the most un-boring place. I just love it."

“The Hangover Part II” hits theatre on May 26.
