Without pretense of being anything other than alcohol/drug-fueled dude humor, this dick flick remains true to the Todd Phillips formula of a few guys episodically surviving a few crazy days with some pretty good gags, scenarios, and characters filling in its cameo-interspersed narrative with few if any periods of comedic downtime, successful in part due to its Memento-like structure keeping the audience wondering what actually happened at the story’s beginning.
Precious Bodily Fluids 
I just saw this and there is nothing special in this movie but if you are looking to spend a few hours to just laugh away and not take anything seriously, sit back, relax, plug this movie in and have a good time.
