Cow's Anatomy

Today we went to lunch with our friends, Cory & Pam Burns.  After eating, we were visiting, so Mikaela started playing a game on my tablet.  She was playing a puzzle game.  One of the puzzles is a cow.  Mikaela was working on moving a particular piece into the puzzle when Cory asked, "Mikaela, what is that?" (looking for an answer of 'cow.').  She replied, without looking up, "It's the bottle."
