Who Let the Dogs OutBaha Men

Baha Men – Who Let The Dogs Out (Original version) | Full HD | 1080p

In the movie The Hangover, a group of four heads out for a night at a Las Vegas casino.

Starting from the scene where Zach Galifianakis—who plays the particularly eccentric character Alan—leaves the hotel room, a famous song released in 2000 is used.

The film may have used it to liken Alan, with his intense personality and unpredictable antics, to a dog.

Although the members of Baha Men are from the United Kingdom, as their name suggests, they perform in a style rooted in the Bahamian Junkanoo rhythm.
