Co worker I work with is a slacker?

So there is this guy that has been working at the same job as I and I try and do get along with him but he is a major slacker! He started just 1 week after I was already working where we are at. I mean he does things when he is told to, but he is still a rookie as I, btw he's white, I am not, the manager is white, and has known the guy for several years now, and the manager is just getting to get to know me. Well this slacker is preferred by the manager. He can get away with almost anything, things that would have gotten me fired. Since at my job we don't clock in just mark our own hours, he marks his all wrong and gives himself more hours than what he really made, it's pathetic, he takes about at least in total just 2 hours of break time each and everyday! and only marks down for the usual halfhour! He goes to the store at least 2 times a day, goes to the porta pottie (Since that is what the work field provides) 2 times a day, smokes 3 times a day, talks on phone, all while working, and plus his Long freaking break time! It's stupid and I do not like him doing that BS. Several co workers have already complained and big boss has considered firing him twice already, but he just gives him chances because of his friend our manager. I know that if I were to do the things he does at work everyday, My butt would be FIRED! So what can I do about such situation? Do I just forget it and mind my own business, not care about what others do? But then again, he is an employee, and is doing Wrong! I want him to be fired already, considering that work has gotten a bit slow lately, and the big boss might give some employees rest time, I want to keep the job, but not with that slacker roaming about. Thank you guys.
