Need advice on response to R-W'er who pulled inappropriate prank

[callous taoboy]

I went to a geology class today as part of my school district's continuing education requirements. The instructor seemed nice, had a good sense of humor and seemed to know how to best reach children. Her suggestions for lessons were good, and she provided each of us(about 50 teachers) a thick notebook of lesson plans and a bag of rock samples.

It was close to lunch time and she was covering a lesson called, "Barnyard Mystery," in which the class has to decide which of four farm animals stole some vegetables based on soil samples taken from their fur, feathers or hooves. Cool lesson. Then she went on to explain that for higher grade levels you can do one called, "Murder on the Beach," which involves the class in a similar scenario as the Barnyard Mystery but with human suspects. She was using her power point and she explained that when she did this one with middle school gifted children she had three suspects, and she presented each one (actual photographs from a magazine) on the screen for us. One was a Hispanic cowboy-looking guy with a caption that said, "Shoot, I got the sand on my boots from cleaning out the barn...". The second suspect was a young blond with the caption, "I was just playing beach volley ball all day and that's why I have sand on my feet...".

The third was President Clinton with a caption, "I did not murder that woman..." The whole class was silent, and then about half of them started guffawing (my colleagues, all but one, included). I was literally stunned by this. I looked at my fellow liberal colleague and she was red in the face and looking at me like, "can you believe this." I didn't hear the rest of her lesson before we broke for lunch because I was seeing red. I did leave at lunch and did not go back. I fantasized about Pie-ing her after lunch, but I can't afford to get fired.

I felt like her prank was low-class, unprofessional and crass. She is connected to geologists who work with the petroleum industry.

I am tired of this kind of shit happening in places where I am basically a captive audience. Last week I walked out on my dentist for having religious propaganda and a huge, gilt-framed poster commemorating *'s second inauguration in his waiting area.

What would you do now if you were me? Blow it off? Let our superintendent know? Also, I have her e-mail address and she is still due some feedback from me re: her presentation. What should I say?
