President Obama's Inauguration & Address.

If for some reason you didn't watch this, you can watch it below. I have to say my favorite quote from his speech would definitely have to be:

...We will not apologize for our way of life nor will we waver in its defense. And for those who seek to advance their aims by inducing terror and slaughtering innocents, we say to you now that, "Our spirit is stronger and cannot be broken. You cannot outlast us, and we will defeat you."
