If you love TV and you love games this site is definitely for you:
http://www.sporcle.com/games/category/television
They have special sections for: Friends, The Office, Seinfeld, Arrested Development, and How I Met Your Mother. And also,more general categories such as TV and sitcoms.
Usually, trivia games tend to be very general and for people that have watched a show more than once, sometimes even too easy. But these are varied, fun, and a bit more specific.
Enjoy the addiction!
