I get that question a lot from people who I've just met. When they find out that I'm a physicist, other than asking what's going on at the LHC, they tend to ask if I watch the popular TV series "The Big Bang Theory". Unfortunately, my answer to that question is "No, I don't".
I know that it is a wonderful comedy depicting scientists/physicists (nerds?), and that other famous physicists have made cameo appearances on the show, but I've never had the inclination to watch it. It's not that I have anything against it. However, my TV channels (and I have 4 TVs in the house) are stuck on HGTV, Food Network, Bravo, TLC, Travel Channel, PBS, BBC America, Animal Planet, Tennis Channel, and Discovery. I normally don't watch any network TV shows (ABC, CBS, NBC, FOX), so that means I don't watch the Big Bang Theory.
Now and then, some of my friends would ask me certain episodes of the show, because they said that these episodes would probably had been a lot funnier if they understood some physics and the inside joke that went along with them. That's probably true from what I've read on the research done for that TV series. I gathered that there's a big college following for that show, which isn't surprising.
Still, I have never watched, and don't plan on watching, "The Big Bang Theory".
