This is probably quite a wide ranging topic and before the inevtable Linehan mention I should point out that I don't mean real life human detritus but the loving comedy creations of those who champion the eternal underdog. I'm thinking Gregg Turkington - from the outright wreckage of Neil Hamburger to the more subtle, deluded sadsackery of his On Cinema persona.
It was listening to Brian Huskey on a podcast today that made me think of this topic, he is a performer I always think of just playing a kind of merry failure, he sometimes veers into creepy or deranged and he can do those well but most often I think of him as Wompler's stepdad, constantly berated, attempting to calmly explain to his stepdaughter that a prolapse is perfectly normal for a man his age.
There's loads of these I could think of but these are the half baked, malformed thoughts that I had the energy to type out so I can turn the topic over to you lot before I lose interest.
Who is YOUR (your) favourite comedy sadsack and WHY?
