this tune was running through my head tonight and I decided to see if I could find the lyrics. My German born grandmother used to sing it to me, so when I first started reading that it was a camp song, I thought, oh, maybe I got it from camp in the 60's and 70's. But when I read it has roots in a german folksong, then I know I am remembering it right. Except that I dont' remember much,

My memory says it goes like this:
My or "Mein" hand on myself, vas is das here?
Das ist mein nose blower, my mommy dear

I obviously can't remember all the body parts, the only one that has stuck in my mind is "brain boxer"

nose blower, brain boxer, rinky, dinky, doo
thats what we learn in da school, jawohl
