Hi all,
I want to share with you this fun article from the NY Times, which gives an algorithm for dividing the rent with your roommates, based on various room preferences. This can be a very useful skill, especially if you are about to go to grad school in an expensive city!
http://www.nytimes.com/2014/04/29/science/to-divide-the-rent-start-with-a-triangle.html
And in case you are skeptical that this will work, you can find a proof of Sperner’s lemma here:

(This lemma is in fact a combinatorial analogue of Brouwer’s fixed point theorem, and it can also be deduced from it).
