Favourite episodes?

I just finished watching this series, and it was pretty mind-blowing. I can easily say that this is one of the best television shows I have ever come across, and I love how quotable it is.

It's hard to rank the top episodes because I loved all of them, but I guess if I rounded them up they would be,

1. "The Planet of the Cats"
2. "People Who Don't Care About Anything"
3. "I Slept With My Mother"
4. "Klan Bake"
