Add the white rum, tequila, curaçao, Campari, pineapple juice, and lime juice in a cocktail shaker with ice. Shake until very cold.
Strain into a beer mug or other tall glass. Add a few drops of red and/or blue food color as needed and stir.
Add ice and garnish with a sprig of mint. Check for blindness and then enjoy.
Note: If you prefer your drinks flaming, slowly pour a small amount of Bacardi 151 or other high-proof alcohol over the back of a spoon and onto the top of your finished, iceless and mintless drink. Use a utility lighter to light the surface of the drink before serving.
