What's the most useless thing you've learned at school?

@FoxyGoddess I love history. I would have loved learning about Tut.

@HowtoDestroyAngels It was neat. I even saw the whole exhibition when it came to America in the 70's. It has only been partially lent out since.

However, I was already 2 grade levels behind in math and should have really been in math instead of drawing the white tiger statue and learning hierglyphics.
