I saw this today while going over old notes from college (not mine, mind).

This instantly reminded me of Rushmore’s opening scene

Isaac: What about that problem?

Mr. Adams: Oh, That? Don’t worry about that.

Isaac: Wait – why?

Mr. Adams: I just put that up as a joke, that’s – probably the hardest geometry equation in the world.

Isaac: Well how much extra credit is it worth?

Mr. Adams: Well, considering I’ve never seen anyone get it right, including my mentor Dr. Leaky at MIT, I guess if anyone here can solve that problem I’d see to it that none of you would have to open a math book again for the rest of your lives.
