Spoilers 

The trivia items below may give away important plot points.

According to Bradley Cooper, while giving a speech at a Toronto screening: "the people in Las Vegas never even noticed [a] movie was being filmed." He said that he had tiger scratches on his neck, all bloodied, and Justin Bartha was beet red, and nobody noticed, or even stopped to double-take.
Ken Jeong improvised the nudity in the scene where he jumps out naked from the trunk. Originally his character was meant to have clothes on, but Ken suggested that his character be naked instead. Later, director Todd Phillips gave Ken a nudity waiver slip to sign in case Ken changed his mind on the nude scene.
In the DVD Commentary, Todd Phillips states that a possible explanation for the chicken in the room is that the guys intended to feed it to the Tiger.
In the MPAA green-band trailer, Ken Jeong is wearing digitally-added underpants when he jumps out of the trunk, and Bradley Cooper says "paging Dr. Douchebag" to Ed Helms instead of "paging Dr. Faggot".
The escalator scene in the casino is a tribute to the movie Rain Man. Zach Galifianakis and Bradley Cooper have to win $80,000 in order to pay back Ken Jeong's character. This is also the amount needed to win by Dustin Hoffman and Tom Cruise in Rain Man.
The same scene is shown at the beginning and end
When Phil, Alan, and Stu go to the clinic to consult with the doctor of Phil's admittance, the doctor doesnt provide much information which leads to Phil bribing him with a $100 while the doctor is washing his hands. The doctor agrees and tells Phil to slip the $100 in his coat pocket because he just sanitized. But in the next scene the doctor is seen holding a file, flipping through papers, and touching the front desk counter
