This tshirt is referencing the character Alan. Alan is the goofy character from The Hangover. The shirt says, "could it be? now there are four in my wolf pack." The movie is about three friends looking for their other friend in Las Vegas after a crazy bachelor party. They get into some trouble with the cops, a tiger, and Mike Tyson along the way. The design features the quote and a simplified version of Zach Galifianakis and has a texture on top of it.
