Use a tall glass and fill with ice. Fill a shaker with equal parts vodka, gin, tequila, rum and the blue curacao. Shake all the liquors together. Then add a splash of lime juice, sweet and sour, and top off with the sprite. Pour into the tall glass and stir to make sure everything is mixed and cold. You can substitute different kinds of rum or tequila to suit your flavors but clear liquors work best.
