Norman McLaren 1914-1987
Keep Your Mouth Shut (1944)
Time: 1 min 42 s

This animated short from Norman McLaren features a human skull cautioning Canadians to "keep their mouths shut" in an effort to end gossiping during World War II.

I found this to be very funny short propaganda film. I can't get enough of the talking skull. I have been wanting to sync some other audio to it, since it would work perfect.
