I stumbled on an archive of great old training movies. This is a General Motors production that talks about how time and motion studies will make everyone more productive.  One hell of a dinner party and a reminder of how much I miss smoking...woe to the poor wives of 1946!

Also in the archive "Duck And Cover!"
