Do your friends think you're stupid? Prove them wrong by wearing this cool Brain Hat by Alana Noritake. It will not only keep you warm but also emphasize your big brains (just like Beardo Beard Hat helps people who cannot grow a beard). Not to mention, it's a an instant Halloween costume when that time of year rolls around.
You can get the knitting pattern of this hat for $5 here, and support "a poor, starving medical student who’s in hopeless debt".
