Take an ordinary face. Your face. Shake it vigourously from side to side. Take a photo of your face as you do this and SHAZZAM! you've created a face shaker.
Pulling a face just doesn't cut it. If the face ain't shaken then it's not a face shaker.

Upload your own and once we have enough, we'll make a stupid gallery of 'em all.

Thanks to babylegschicago on flickr for providing the above photos to kick this off.
