Student SF appreciates that he's got a professor that likes Shameless as much as he does. Here's a list of other shows I like:
If you're looking for older stuff to pick up, try Sons of Anarchy, Srugim, Curb Your Enthusiasm, Arrested Development, House, Wilfred, Breaking Bad, Treme, Hung, Little Britain, Big Love, Deadwood (I think the first season of that is the best thing that was ever on TV), Sopranos, Oz, Sex and the City, Tracy Takes On ..., Slings and Arrows, The Larry Sanders Show, The X-Files, Simpsons, or King of the Hill.
P.S. I regret that I didn't discover The Late Late Show with Craig Ferguson until he'd been on for about 4 years. They never repeat stuff like that.
