As with any great university, GNU is an intensely competitive place for advanced mad scholars in training. Frostbite Falls is not the largest metropolitan area in the country, by far, and so there is by necessity a certain culture of self-experimentation amongst the doctoral students. The ones who make it to the end of the program appreciate the skills that develop from the constant trickery involved in acquiring lab subjects... and avoiding becoming one themselves. But at the end of the day, it's all about science, and sometimes a mad scientist has to take one for the team. It's a matter of dedication... to SCIENCE!! Ahem.
