Step 1: Get your can and glass ready.
Step 4: Look at what is left in your glass: Guinness would rather you drink an entire glass of this. Once you finish what is left, you will realize they are wrong and that it was far superior while leveling.
Since this blog is also about TV, I'll just cover my bases by saying almost everything on Thursday was a repeat. But feel free to go to http://www.guinness.com/, click on "The Beer," and then select the glass of Guinness. There will be a side bar that says "How to Pour the Perfect Guinness." Watch that video and note at 27 seconds when he says "stop," that is when the glass should be filled the rest of the way and then instantly consumed.
