Pen Card - 340 Cipher

Sorry I haven't written,
but I just washed my pen ...
and I can't do a thing with it!

This is the Zodiac speaking
I though you would need a good laugh before you hear the bad news
you won't get the news for a while yet.
PS could you print this new cipher on your front page?
I get awfully lonely when I am ignored, so lonely I could do my THING!!!!!
