I rarely, if ever, watch sitcoms. They're usually full of bad language, bad morals and generally unproductive.
Normally I watch Mythbusters, Dirty Jobs, future weapons or some history show on the history channel or national geographic.
If it's a show on WWII that's been on the history channel in the last 3 years, I've probably seen it
I also sometimes watch bird hunting or shooting shows on the outdoor channel.
