Dad suggests a sherry 'To keep us both going', in the cosy front room with the firelight glowing ... Then out comes the Baileys. And mum hits the rum. Hours of merriment and a stocking-clad tango later, they drift off to sleep - the living room in disarray, the presents unwrapped and their careful Christmas preparations in ruins.But come morning it seems a mysterious visitor has saved the day .This tipsy twist on the nation's favourite festive poem is the perfect gift for harassed parents everywhere.
