The informant related an activity she did with her children.
When I was a real little girl, My grandpa used to put me on his foot like this and hold my hand. [She crosses her legs at the knee and holds her hands at about knee level as though holding the hands of a toddler.] He was Norwegian and he would sing: “Ah ria ria runken. Hasta netta blunken” [phonetic transcription] [She mimes bouncing the child every other syllable.] I have know idea what it means.
I find it interesting that the informant remembers and passes on this piece of folklore despite not knowing even what it means because, even though she does not speak Norwegian, she is sentimentally attached to the rhyme.
