I’m self-taught in C++. I took a class in it (AP Comp Sci) in high school, but it doesn’t count. The teacher knew absolutely nothing about programming; she was a Physics teacher who was given the class because nobody else would have it. Her qualifications were a one-month Java course at the community college and a copy of C++ for dummies.
Being of the sort that picks things up quickly, I flipped through the textbook, downloaded DevC++ (an open-source compiler), played around a bit, and figured out what I was doing. From that point on, I taught the class…literally. If I couldn’t figure out how to do something (read: if I didn’t feel like doing it), the class skipped that project. I gave the teacher a couple after-school lessons on different ways to accomplish upcoming projects. It was actually quite fun.
French I-IV were like that too, although I can’t quite make the same claim, since my teacher did in fact speak fluent French. It’s just that the class was full of morons who, despite having it pounded into their heads for four years, still couldn’t conjugate être (“to be”) from memory. Come on, people! We’re into the subjunctive and past perfect now, and you can’t $@%!ing conjugate “to be”?
I think my tendency to make outbursts like that were a large part of why the teacher allowed me to spend the class in the library, doing whatever the hell I wanted to do, as long as I showed up for the tests and maintained an A average. Because of that arrangement, I include French on the list.
I’m self-taught in philosophy, if you count the formulation of one’s own ideas as an “education”. I have a fairly comprehensive framework of interconnected beliefs, as well as ideals as to how to formulate and analyze such ideas, all of which comprise the fundament of my future endeavor I’m calling the Freedom of Thought Movement. Not exactly classical philosophy, but I came up with it on my own, so it counts.
I’m also trying to learn guitar, but I swear the accursed things were created by someone with fingers the length of Shaquille O’Neal’s and the width of a baby’s. Then again, I can play a C, an A, and a D, and that was good enough for the Beatles, so… 
Cheap shots at the Beatles aside, that’s all I can think of for the moment. As far as I’m concerned, self-teaching is the way to go if at all possible. It provides a far better understanding of the subject at hand than simply learning from lectures and a textbook.
