Excellent Evidence - Renata Adler

I'm currently reading Renata Adler's Speedboat and came across this paragraph that, I thought, made a pretty excellent prose poem all by itself (a common occurrence in Adler's work, to be sure):

Excellent evidence. "The source said that the investigators considered the responses of the dogs 'excellent evidence,'" the Times reported. "In each case the two dogs reacted positively to Mr. Hoffa's scent. One by standing up," the story went on, "and the other by sitting down." Since Will is a lawyer and I used to be an investigative reporter, we conclude that the dogs went to different schools, one to a sitting school, one to a standing school, but anyway to different schools.
