I know - me too*tongue emoticon*I just make a habit of treating
  sarcasm as literal, partly for the "oh he doesn't get it's a
  joke, does he?" for those that automatically laugh, and also as
  a challenge because there could be times when the same words
  could be asked of me by someone who _isn't_ being sarcastic and
  I'll need an answer. Plus I get amusement when someone says, "I
  was only kidding", for just as I was to see the other person is
  kidding, they too are supposed to see that I'm kidding in my
  serious response. Yet, I don't expect it because I'm giving a
  mixed message while being straightforward. There*smile

  occasions. I think it's "dry", yes. Dry - yes, that's what they
  call it. Silly categorizing humanity.*tongue emoticon
