The usual Halloween episodes of course are included in my list, like The Secret of Parker House and Halloween Knights, but sometimes I'll also watch other "creepy" or "supernatural" themed episodes such as Ghost Ship, The Visitor, or Cleo Rocks. Anything with Murdoc in it is perfect for Halloween viewing.
Oh--I'd also add Walking Dead and The Lost Amadeus, because one is "scary," albeit in a cartoonish sort of way, and in the other (if you can stand Lulu), he dresses up for a costume party.
"If a man does not keep pace with his companions, perhaps it is because he hears a different drummer."
