To split the G you must have a pint of Guinness in a Guinness glass. The objective is to have the line of the pint (where the black and white meet) between the bottom of the harp and the top of the G after the first sip of your lovely pint. This is advanced way of playing the game but the only way real men play. Sláinte!
Macauley bet John he could split the G on his first attempt.. And failed

Refers to taking a substantial enough first gulp from a pint of Guinness that the level of the remaining beer in the glass is directly through the middle of the "G" in the word Guinness, which is printed on the glass.
I can split the "G" when drinking a 16oz American pint, but have yet to do it with a 20oz Imperial pint.
