hmmm. It all depends on your goal. Potential ways of doing it include:
1. Sending email that you're not coming to work anymore (if you really couldn't care less what future references will say about you)
2. Telling your boss "I quit" on your next meeting
3. Saying "I'm exploring some options, I want to try new things, it's not you it's me" and letting them down easily (but stay firm)
4. Coming to work in your flipflops and bathing suit for a few weeks until they fire you and you get severence pay as well. If that doesn't work, escalate - bring your goggles. Or sunbathe to the neon lights of the office, right next to the watercooler.
5. For extra credit, tell them you're taking a three month vacation to go see venezuela and to get a little high. Insist the vacation starts in a week. Insist that they keep paying you. They'll just HAVE to let you go.
