A few months ago Sarah Palin said President Obama doesn’t have the cojones to deal with the issue of illegal immigration. If she runs for president in 2012—did someone say “if”?—she might want to make sure she chooses a candidate with cojones grande. Like the Tuberous Bushcricket for instance. Biologists at the University of Derby, England, report that the Bushcricket has the largest testicles in relation to its body weight in the world, weighing in at 14% of its body mass. To put that into perspective, if it were a human male each of its testicles would weigh as much as five bags of sugar. But make fewer batches of chocolate chip cookies. What the scientists haven’t determined yet is why they chose a career that entails weighing animal and insect testicles.
