Hands down best commencement speech I have heard

I stumbled upon Conan O'Brien's 2011 Dartmouth college Commencement Adress online. When I started watching it, it was background noise for work, but as the speech proceeded, I found myself glued to the screen and had dropped everything that I was doing. It was a fabulous mix of comedy and hard truths. The comedy was what I expected, but the serious message delivered seriously was the highlight and earned him a standing ovation.
