If you find that creating your role-playing character's backstory a little rough (thanks to your sense of imagination being dulled to a smooth sheen), the internet — as always — is here to help.
Who The Fuck Is My D&D Character is a generator (via Super Punch) made by Ryan J Grant that will do as advertised. Click a button and you'll get a complete backstory. Race, origin, background. If you're not happy with it, click it again, and again, until you get something like this.
You may not be the most dangerous character in the game, or the most helpful, but at least you'll be the most interesting.
