Not in any particular order, but when I do get the rare chance watch TV, I like:
Deadliest Catch, Futurama, Simpsons, South Park, Boston Legal ("Denny Crane"!), Commander in Chief, According to Jim, George Lopez, Less Than Perfect, Frasier reruns, Most anything on Discovery Channel, and occasionally Food Network (though it seems to be getting away from what it was in the beginning.
