When liquor is involved, I drink cheap stuff because, hey, I'm broke!

Vanilla vodka and Diet Sunkist Orange
Vanilla vodka and Diet Coke
Canadian Club (or Crown if I've got some cash) with either Diet Coke or Sprite Zero
Captain Morgan and Diet Coke
Blueberry vodka and Sprite Zero

As for shots...Liquid Cocaine, Dead Nazi, Goldfish, Crown, or pretty much anything that's sitting in some rockin' cleavage.
