What is the right way is to do the Guinness Challenge .
Some people are 'split the G' die hards, meaning they reckon a successful Guinness Challenge is one where you get the line between stout and head in the middle of the 'G' in Guinness..
The 'split the G' crowd faces stiff competition from the people who reckon the right way to pull off the Guinness Challenge is to drink until your line is between the top of the G and the bottom of the harp..
People can agree you're supposed to pick up your pint of Guinness and keep drinking in one go until you think you've reached the right spot with no pauses or tilts to check your progress..
I have contacted Guinness for comment..
