I hate math. I crammed my senior year in high school with AP Calc and AP Stat for the sole purpose of never again having to take math in college. Some of the classes were okay, but I despite the subject of math after basic algebra.
EDIT: However, I have to say I hate "fake math" - such as Statistics - even more than math. I even liked Calculus for than Statistics. As...someone here said, no one should be allowed to do Statistics without first integrating the normal curve by hand.
I also remember an intense dislike for Spanish class. I didn't have anything against Spanish, I just really hated the class.
