Well, what can i say about it.. .the worst movie i have ever seen. ..One will find Sajid khan who used to make fun of other directors who used to copy the hollywood films  has himself stolen the concept from hollywood films like baby's day out and three men and a baby . as i have mentioned earlier its a trash movie with all double meaning dialogues and not so funny jokes to laugh at and so much of indecent picturization which literally tortures and one more thing which i forgot to mention is the acting, no actor's performance is worth appreciating except for fardeen who has a small role but played it very nicely and also the  baby girl ofcourse the cutie pie's expressions take the cake..and she is the only plus point of the movie

The film is just like its title...its full of masti..The story revolves around three friends meet, prem and amar( played by vivek, aftab and ritesh)  who are quite fed up with their wifes (that is amrita, genelia, and tara). It all starts when these three friends decide to have a reunion and first they pretend to each other that they are quite happy with their wives but then truth is out.  They find themselves  in the same situation and so they decide to have an  affair.   After so many failed attempts they finally end up having affair with the same girl that is Monica (lara dutta).  This is when lara dutta comes into picture.  She asks them to get money from their wives and blackmails them that if they dont get money then she would show their photos to their wives. somehow they manage to get money from their wives. before they could think they are out of trouble, this time they find themselves caught in a even more serious situation when they discover that (Monica) lara dutta is murdered and they try to run from the place and at this point, Sikandar who is an inspector ( played by ajay devgan) comes into picture.  He keeps an eye over them and moreover the murderer also starts blackmailing them.  no no people iam not going to give away the whole story. Its  a surprise ending and u have to find it out just watch it and enjoy. its a fun film.
