Reading: 

From Wei-chen Huang's MA thesis "A Study of Verbal Morphology in Puljetji Paiwan" (2012), p. 35. 

I am reading this thesis now, and I quite appreciate the way this author shares his Paiwan knowledge in such a responsible manner, well structured and soundly founded. His exmaple sentences are also more interesting than those of most other books of the field. Is this Rolling Stone sentence perhaps one of his inside jokes?
