This is once again a funny and nice movie from the same guys who gave us Shallow Hal and There's something about Mary - Farrelly brothers. This movie is quite decent,funny and nice to watch. Matt Damon and Greg Kinnear play the lead role and have done a neat job.

Bo (Matt Damon) and Walt (Greg Kinnear) have been joined at the hip since birth, and, since they share a liver, there is danger associated with an operation. So they stick together, and muddle through the difficult and embarrassing times. One day, Walt decides that he's no longer happy flipping burgers in Martha's Vineyard. He wants to go to Hollywood to become an actor. Bo isn't excited by the idea, but, since he doesn't want to hold his brother back, he agrees. Walt's initial forays into the thespian world are disappointing, but then he meets Cher (lampooning herself and her image). She's trying to get out of a series she is contracted to appear in, and figures that if she makes a conjoined twin her co-star, the producers will shelve the program. But the strategy backfires. The series is a hit, and Walt is a star. Unfortunately, his brother's success is Bo's failure, and things get worse when his Internet girlfriend, May (Wen Yann Shih), discovers he has been lying to her. Now, all Bo wants to do is go home, but he can't do that as long as he is connected to Walt.
One of the nice dialogues is when the brothers sunbathe with lovely eva mendez on the beach and she asks why they didnt opt for a plastic surgery to seprate them. Then Walt replies that they both share a liver and Bob owns most of it and doesnt want Greg to suffer consequences of a surgery. It was funny but yet touching...
Watch the conjoined brothers share their fortunes and troubles!!
