I Love You, Man (2009)

Peter Klaven, a real estate agent, is getting married to Zooey and realizes he doesn't have a friend to ask to be his best man. So, he starts going on a series of dates to find someone to fill that role and meets Sydney Fife and they immediately hit it off. Only this new friendship throws Peter and Zooey's relationship off balance. A very funny comedy with likable characters, physical humor and great chemistry between Paul Rudd and Jason Segel. If you're looking for a comedy that will make you laugh, this is the one.
