I've been ranting and raving about this guy in my class the last few weeks because he's an arrogant jerk. I sat next to him once and I vowed never to sit with him again. (My friend sitting across the room told me that I had the scariest scowl on my face during the entire time.) Thankfully, he left the class last week. Hurrah!
Ranting about him reminded me of a video by Lev Yilmaz about arrogance and confidence:
Arrogant people are socially retarded. Punkt.
