DO NOT UNDER ANY CIRCUMSTANCES start watching Lost on netflix. I made this mistake a while ago, first 2 seasons seemed cool as fuck, and then by the end of it you are just watching it compulsively, not enjoying it a bit, waiting for the series finale where your questions finally continue to go unanswered.
Arrested development is good, so is 30 rock, breaking bad, and dexter if they still have the first few seasons on there. Otherwise there is a shitload of really good old nickelodeon shows (hey arnold, ahhhh real monsters, etc.) and some really good stand up comedy.
Remember when the signatures were the same shade as the posts, and you used to be able to trick people. And if you are reading this, it is my sig.... Those were the days.
