Turb O'Shandy Cocktail
A variation on the ever-faithful Turbo Shandy, this is the Irish species. Take your half-drunk pint of Guiness, and pour in a bottle of Smirnoff Ice (preferably black) slowly. Give it time to settle. Bung in a shot of Vodka if you want to die. Tastes a hell of a lot better than it sounds and guaranteed to make you giggle, gurgle and gag. The gentleman's turbo choice.
