Friends
Scrubs (Just put it on Netflix so watching it all again, if you havent seen it you're missing out)
Pretty Little Liars (fantastic early seasons, gets worse as you go along though, but still good and on Netflix they post the new episode the same time that they come in America. And I've heard it's better when you binge watch it, whereas I've watched it from the beginning so have had too much time to think about the billions of loop holes :L)
