Some time ago I wrote a post that questioned the practical feasibility of electing a U.S. president with openly diagnosed bipolar disorder. I caught some flak for that, but I have changed my point of view only today, thanks to this mind-blowing story by The Onion. This changes everything. Vice-President Biden is helpfully diagnosed as well at the end of the first clip. If President Obama starts to put on a lot of weight, we'll know why. (No, this is not a cheap shot at bipolar disorder; it's merely hilarious).
