The most BS? Oh, that's easy.
You see, we had a couple very retarded Geometry class traditions and one of them was where we had to make these origami shapes. The first ones were somewhat easy like a tetrahedron but later on in the class we had to make much more BS shapes like these: http://en.wikipedia.org/wiki/Compound_of_five_octahedra
And let me tell you, some of those shapes took a long time to make and even THEN, it was really easy to screw the later ones up. And what geometry lesson did I learn or what lesson was I supposed to learn? Not a darn bloody thing. Now don't get me wrong when I say what happened next. I am NOT a habitual cheater by a very long shot but, heck, the whole project was so bad, it was one of the only assignments that I ever cheated on in my life. It sucked so bad that I felt that using some of the other shapes that past graduates had made was perfectly justified.
I got caught in the end so I still had to do them and in a more limited amount of time too but man I hated it so much. Don't even get me started on the other fag projects I had to do for that horrible class. >.>
