These are all great! I have many fond memories of my grandfather leading this song. This is our family's variation.

I place my hand on myself.
Vat ist tat der?
This is my dummkopfer, yes darling dear.
Dummkopfer, better-nedder-knocker-now,
That's what I learned in my shool.

Duumkopfer (top of head) [apparently means dumbhead in german]
Sweatboxer (forhead)
Eye Browler (eyebrows)
Eye Blinker (eyes)
Snot Blower (nose)
Soup Strainer (top lip)
Bullet Shooter (bottom lip)
Jaw Breaker (jaw)
Rubber Necker (neck)
Chest Protector (chest)
Bread Basket (belly)
