Just twice for me, in a long career of pool I have managed this holy grail. God it feels good. And the first time wasn't against a man absent skill. He just fucked the break and then I cleared up. When it was down to final balls him and his mate started cussing my mother, calling me out on personal hygiene- the works. All to break my nerve. After such ungentlemanly and unsporting behaviour I felt entirely justified in doing two victory laps round the table and saying 'seven balls bruv, you've took a hell of a beating' the thrill of victory!
