Brass Monkey

1 x Shot Vodka
1 x Shot White Rum
Orange Juice
Ice
A Tall Glass

A friend to drink with (or failing that any idiot you can drag in off the street)
Fill the glass with ice before adding the Vodka and Rum. Top up with orange juice and stir well. Its as simple as falling out of a tree, which should prove very simple after a dozen of these cheeky chimps!
