So I just talked to my Market Research professor about the textbook, because we found an error* in class and he mentioned that he would have to tell the author about it.
He had mentioned before that he knows the author pretty well**, so I told him after class that I had found a few more errors (including a couple not mentioned here) and asked if he wanted to forward those along.
His eyes lit up and he rubbed his hands together. "Oh, yeah," he said. "That would make him really mad."
I like my professor, but I'm not sure I want to be encouraging that kind of behavior...
* Which I didn't think was an error as much as a really, really dumb hypothesis.
** It turns out they are writing a textbook together on another subject.
