Have you ever noticed just how nasty most sitcoms are? How characters fail, fail and then fail some more, before suffering some more.
But which is the meanest and harshest?
Malcolm in the Middle, every one in that show is a loser and a victim? The episode where they feed Dewey dogfood, then make him shit on the lawn?
or
Peep Show, where the 2 characters had break downs in the first series and were reduced to alcoholic wrecks stalking each other in their flat?
Perhaps Neil's life of misery in The Young Ones? Buried in the garden, nailed to the floor and worse.
