I always get the feeling when I read either Harlan Ellison or Philip K Dick that they're giggling to themselves at some knowledge that they have, that no-one else has. They both play with form, straddle the line between puerile and innovative, and seemingly come up with original ideas with a wave of their hands. They're both definitely in my favourite author list, of any genre.
