"Pretty good all right"
This was such a common expression. A search on the Web for both it and a string incorporationg "alright" resulted in discovery of just one reference: the transcription of a conversation in English from Fort Apache (Cibecue) in Arizona, date not noted, in which this phrase of approbation is recorded several times. It's on-line course material for Indigenous Perspectives I: concepts of humor, a distance-learning project of the Institute of American Indian Arts in Santa Fe. Where does this expression come from? A movie? We heard it among Navajos and Zunis, and then there's the on-line example from Arizona Apacheland. Is it peculiar to New Mexico and Arizona? I can't remember what we were talking about that brought it up.
