[I have the worst headache right now, and I'm not sure if it's from a lack of caffeine or too much caffeine. I'm feeding it coffee and Excedrin Migraine to see if it will go away. If anything, hopefully I will shortly be in a better mood.]

the bomb. I couldn't have written it better myself. Apparently, this guy actually turned this in. I'd have given him an A.
