I reached into my bag of meaningless methods and chose a winner for Nature Anatomy: The Curious Parts and Pieces of the Natural World. Here is how it worked:
Write down the posted times of all the comments.
Ask child number 1: “am or pm?”
All the PMs got crossed out. Sorry!
Ask child number 2: “8 or 9?”
All the 8s got crossed out.
Ask child number 3: “11 or 47?”
47 takes all.
Mary, who commented on the post at 9:47 am (PST) wins!
Congrats and I hope you all tune in for next time!
