The CW may have kicked off its fall season on Labor Day, but for most of the other networks, things are just getting started. So what does that mean for you? Heavy promotion for not only the new shows premiering this fall, but for returning favorites as well. To that end, My Name Is Earl creator Greg Garcia and star Jason Lee spoke with reporters recently about Earl's upcoming 4th season.

My Name Is Earl returns for its 4th season on NBC with two back-to-back episodes, September 25 at 8pm. Not only did Garcia and Lee give us a taste of what to expect when we catch up with our favorite Camdenites, but they also dished the dirt on dream guest stars, what previous guest star peed over by craft services, if an Earl movie is in the works, and perhaps a word or two about a famously abrasive 30 Rock star. All of the details are after the jump.
