The Go Fuck Yourself Shandy

1 part ginger ale
1 part malt liquor

A shandy is a popular beer cocktail that mixes beer with ginger ale or lemonade. Drink your 40 halfway down, then fill the rest with ginger ale. If you use a ginger ale that's fresh from the fridge, you get the added bonus of chilling your 40, which may have warmed slightly as you drank.
