Christmas presents for your biology teachers

Colin Purrington is an associate professor of biology at Stawrthmore College in Pennsylvania, and he is increasingly displaying the personality traits that we Australians refer to fondly as "shit stirring". Colin is responsible for the extended "textbook disclaimers" that have had a fair bit of press lately. He also did a genealogy of textbook disclaimers that found its way into the New York Times, with the help of cartoonist Felix Stockwell.

Now he has turned his satirical talents at listing present suggestions for beleaguered high school biology teachers who may be feeling the pressure from creationist parents and school board members. We sometimes forget these poor folk on the front line. Buy one of these items today for your child's biology teacher...
