Qui a volé les biscuits de la boîte à biscuits?

There is always a lot of sharing of brain breaks in the CI community. I began seriously implementing them about two years ago, and man, are they great! Fun, essential, and community-building. If you haven't visited La Maestra Loca's blog to see her amazing collection, do that now. (Well, as soon as your done reading this post!)
One of my students' favorites is a game we call Qui a volé les biscuits de la boîte à biscuits? This is one that can run a little longer than others, but I still love to do it once or twice a month. (It's in the Mafia/Bad Unicorn vein.)

This video on the left (which is only three minutes) shows an entire sequence of the game, from me putting the cookie in a student's hand to students guessing until they find the culprit. 

This video on the right (less than a minute long) just shows a couple of rounds of the song.

The basic idea is that students sit in a circle, close their eyes, and place their hands behind their backs. I walk around the circle and place a biscuit (a little fake cookie that a friend baked for me) in the hands of one student; the cookie should be small enough for students to cup it in their clasped hands. I then tell them (in French) to put their hands in front and open their eyes. They then sing the chorus of the song, and students start to guess who they think stole the cookie.
On the the left is the slide I show to introduce the song.

The text of the song in English is 
Class: Who stole the cookies from the cookie jar?
Who stole the cookies from the cookie jar?
Students raise their hands and I choose a someone to name a suspect:
Class: _______ stole the cookies from the cookie jar. (The accused's name fills in the blank.)
________ stole the cookies from the cookie jar.
Student accused: Who, me?
Class: Yes, you!
Student accused says either: Yes, me or Not me!
If the student isn't guilty, the class says, So, who?
We keep playing until the guilty student is found, or I decide we need to stop, in which case students put their hands behind their backs, close their eyes, and I retake the cookie to play again another time (that student will get the cookie a different time). Because I teach younger kids, I have to keep track of who has had the cookie, since everything has to be "fair!"
Let me know if you try this, and what you think!
Bisous.
