IT 

The abbreviation for the Institute of Technology at the University of Minnesota. IT students are known for being dull and relatively uninteresting. They are about the only ones in the world who count as the highlight of their weeks as successfully compiling a program that converts temperature from Fahrenheit to Celsius in C++.

An IT student's shirt:
"There are 10 types of people in this world: Those who know binary, and those who don't."
