Elvis Aaron Presley. The King of Rock'n'roll. Elvis is credited with bringing coolness to the people of Earth. Without Elvis, all that we hold dear would be nonexistent.
Hopefully, for your sake, you already have your own personal relationship with The King. If not, I highly recommend that you begin cultivating one right now. It's not that hard. All you have to do is make the conscious decision to be awesome. If you achieve true awesomeness, Elvis will come to you. Once you've seen the light you will be blessed with true coolness. And you know what? When you're truly cool, you're cool for the rest of your life.
However, if you're having a hard time being awesome you could buy some Elvis CDs to get you going on your road to coolness. I'd check out the Elvis Presley: Artist of the Century 3-disc box set if I were you.
