Saatanan Kyynel (Tears of Satan)

What you need:

All the Gin you can find
All the Bourbon you can find
Some carbonated cola drink
A container of some sort

What you need to do:

Put the container on a table and pour in all your gin and bourbon. Fill the rest of the container with cola (the size of the container determines the alcohol content of the mixture) and mix with something (your hand, if nothing else is available).
Enjoy.
