The premise of this movie has been done to hell and back, so, there is really not too much to add to this, two guys, one married and another single, one full of responsibilities and the other completely childish and sex addict, both best friends and a night of "pee" in the right fountain gets them a switch of bodies.

The movie starts OK, really, with such a stereotypical premise there is nothing surprising, the married man is alright, the childish man is totally unbearable.

Once the change up takes place, both had to endure their new lives and in the process they find each other and more Hollywood blah.

The movie has nice comedy parts and some really gross moments, which is sad because the ending is about to change all that.

If you see this movie from start to middle you will think this is a passable to mediocre movie, some gross jokes are barely watchable being "the finger" part one of the gross of all, I almost turn it off in that part.

But suddenly, out of nowhere, in the last 30 minutes of movie, this all passable show become incredible hearth-warming and soft, it's like the director found it's way in the end and although cliché it just ends great.

It's too sad that the gross parts will prevent this movie to be seen on a greater audience, and frankly, if not for the ending, they would be somehow justifiable because, well, this is raunchy comedy.

The thing that really bothers me about this one is that the last 30 minutes are really great, a really feel-good moment and totally likable so, this last part changed the perspective of the whole movie (in a good way) and then, the raunchy parts becomes totally unnecessary.

If they could just make a nice comedy the whole time instead of raunchy- dirty in the first and second act and super heart-warming on the last act this would be one of my favorites, but the mixing became somewhat wrong.

Hapily, the best part is in the ending so we can forgive some of it's flaws.

6 out of 10

Do not recommend seeing this with the family but it's OK for singles and couples although I will just skip the finger scene altogether.
