Watch I Love You Man Online For Free

Where can you watch I Love You Man online for free? I want to watch I Love You Man online because I have nothing to do this weekend and I might as well watch a funny movie at home. Among the films opening this weekend, I Love You Man is the only comedy that I like. Yes, there's Duplicity but I think it's a bit serious for me. I think I better call my friend who wants to watch I Love You Man also and ask if we could watch it together.
