|Billie and Mister Holiday.|
The 'direct-via-email' winner was the ever-spectacular Mistress MJ, who sent me a message with the answer mere minutes after the quiz was posted.
The 'guess-in -the-comments' winner is the lovely and demure Donna Lethal, who mentioned a resemblance between Mister and her pooch Chester. Now that she mentions it, I can see it.
For being the first answer MJ will receive, for her prize, on her next visit to Hollywood, a nice long walk. Walking tour, that is.
