Brains Brains!

So the other day I was cuddling Catie and her enormous head and I tickled her, telling her, "You pretty little thing with a giant head.  You better hope the zombies never get you, they'd be all over you and that big ol' brain of yours!"  And for two days she has been telling me, "Oh no!  The zombies get me!"  and squishing her face into my shoulder.  I giggled the first few times and feigned horror at the thought... then explained multiple times thereafter that it's just pretend... and now I think she just does it so I will give her a squeeze.  I'm fairly certain that my two-year-old has no idea what a zombie is, but she her fathers daughter after all.
