Has anyone tried rum,, whisky,, vodka and coke ?

Sounds like amateur hour.

I've never done that -- Not a good idea to mix light & dark alcohols in the same drink.

I was associated with a Country Club for a couple of years, and some of the members organized a golf tourney called the "moose juice open". Moose juice was the beverage carried by each two man cart in the tourney. Moose juice is 750ml each of Tequila, bourbon, scotch, gin and vodka, along with a bottle of cold duck. You could tell the mixture was correct by the fine purple mist coming out of the cooler when the duck was added. There were unusual awards given such as longest drive in the wrong direction, passing out closest to the 18th hole, and most cart collisions. The tournament was distinguished by being asked by each course where it was held to never come back.
