I Wouldn't Even Mention It

Did you know I am serializing a novel on the "internet"? "Click" here if you don't believe me! You'll feel pretty dumb then! It's called SOUR BLUEBERRIES. It's sort of a companion piece to my previous limited-edition novel SWEET BANANAS, which is made of actual physical substances, and of which there are still a precious few copies left if you ACT NOW. I wouldn't even mention it, but as I was "posting" this morning, I noticed that there is an owl in today's installment (Part 10) of SOUR BLUEBERRIES. And you know what that means. Who are you?
