Pet intelligence wank
The Guardian: Cats outsmarted in psychologist's test.

You can imagine how well this goes with the readers. Besides the predictable flood of pet owner butthurt and anecdotes of clever / stupid cats / dogs / mice / owls, there are plenty of genuinely funny comments as well as a side wank on the validity of test methods and statistics, obligatory calls to talk about world hunger instead or discuss the intelligence of various nationalities, and, naturally, Hitler and his pets make a bonus appearance. I think one could play classical wank bingo in here, but some of the stories make it all worthwhile.
