Which sitcom is your most favorite?

Tweet

I just had a two-week holiday and I stayed at home for sitcoms to relax myself from heavy work. When I surfed the internet to find something new to watch, I saw a discussion on the best sitcom ever. And many people have voted to "Friends". I do love the show, but I've seen it for many many times. So what is your favorite sitcom? Please give me a little more information than the names, cuz I really wanna some new wonderful shows for my holiday. Thank you.
