This reminds me of the anecdote about the math student who showed up late to a lecture and saw three equations on the board; he assumed they were homework, so he copied them down and worked on them. When he came to the next class, he said, "The homework was really hard; I could only solve one of the equations," to which his professor replied, "Those weren't homework--those were three of the most renowned unsolved equations in the field of mathematics." I forget where I read this, but I have always chosen to believe that it is true, because, damn... that's awesome.
