Unrated Version - What the hell? (SOME SPOILERS)

I saw the theatrical version of Sex Drive last week and thought it was a good movie and would be worth to rewatch some time. So I got the unrated version, and boy, what the *beep*?! Naked chicks in random scenes, a guy's dick to act out as Lance's in the scene where they run from the redneck?! Also we get to see bloopers in the middle of the film, you can hear the crew laughing and even see part of them standing in the garage scene. Apart from all this the thing that disturbed me the most were the farts! How immature can you get if you put random farts in scenes that show butts? These things made the Unrated version unwatchable. I understand that it was just a joke from the makers but I expected it all to be very different.
