Mostly these days we like... some old comfortable sitcom reruns, a couple of daily game shows we get a kick out of, whatever Nature/Discovery/History type channels are offering for documentaries (we are nerdy that way), some random offerings on The Food Network (get ideas) and now, of course, hockey.
We always watch out for good movies to record and watch on PVR later as long they are not on channels that omit and bleep out the "naughty" scenes/words.

Just watched Shrek 3 (again!) the other day and laughed like hell at some of the silly bits kids would not pick up on but are there for the adults.
I guess we are boring when it comes to TV as we avoid drama shows (news is dramatic enough), hate reality shows (soooo scripted and dumb) and we are just not into zombie/sci-fi stuff. Never have nothing to watch though and the PVR always has many hours of stuff we haven't watched yet.
Edit:
Just noticed DrC's post about Battlebots. Fun show to watch for sure!
