Brought an English friend of mine into the Porterhouse once. I ordered a pint of Wrasslers then looked at my friend and he asked for a Guinness. The barman threw his eyes up to heaven, looked at me and said "sort that man out will you". I said two Wrasslers and we had a great laugh, all the while my English friend looked on confused. By the end of the night we had taken a sample from pretty much every tap (sample not pints, friendly barman) and I had another convert.
So what we need to do is individually bring every single person over the age of 18 in Ireland out to the Porterhouse and spend the night convincing them that Guinness is not the greatest drink in the world. Then and only then will our dreams of a beer utopia come through. OK, how many people are on the site, I'll grab a phonebook and we can start divvying up the population.
