In the car today, C starts singing the ever annoying, will never go away song as follows:

Mommy stole the cookies from the cookie jar!
I'm expected to respond with "Who me?"
Yes you!
Again, good parenting requires me to say, "Couldn't be!"
Then who?

And then we name another cookie stealing suspect.  We go through a round or two of C blaming me, me blaming C, then she decides to throw in her sister.  "E stole the cookies from the cookie jar!"  and clear as day from the back seat, we hear an incredibly defensive and shocked, "NOOOOOO!  I DIDN'T EVEN HAVE ANY COOKIES TODAY!"
