There are a couple of shows that we have found that we both like. These include: Seinfeld, How I Met Your Mother, and Friends. They are all sitcoms and keep us laughing.
We like to buy the seasons so we can watch them whenever we want. Seinfeld and Friends don't ever make new episodes, so it's nice to have them to keep forever (at least until they quit making DVD players and then it'll be on to the next biggest thing).
I found season 7 of How I Met Your Mother online and I'm going to order it as a late Valentine's Day surprise!
