Heh. My math, science, and computer teachers were all pretty good. I do remember one test in college physics. Basically, we had to calculate how much energy (from the sun) was used to melt snow off of a rooftop. Fairly simple, right. Well, I figured it all out, and came up with a number that was large enough to power a small city. "This can't be right!" I thought. So, I finished the test, and went back to that question. Worked it all out again, and came up with the same answer. So, I left the answer, and under it I wrote, "There's a problem with one of the variables you gave us, because this is enough energy to power a small city."
The rest of the class saw the same thing, and thought they did the problem wrong. So, they all erased their answers, and left that question blank. The teacher realized his mistake, and didn't count that question. However, myself and one other person got extra credit for (a) answering the quesiton properly, and (b) realizing that the answer itself was wrong for the problem at hand!
