I don't have many spin geeres around me now, man ... :S One of my favorite professors is one, though (well, actually I've never had a class with him, unfortunately, but will be this coming Fall, ka khairee! :D), and I tell you I enjoy my time with him SO MUCH! It's like, once I'm with him, I don't wanna leave and wanna let him talk on and on and on ...!
