Cowboy Roy

It occurs to me that no one knows what a Cowboy Roy is. So, the recipe:

vodka
rum
orange juice

Yeah, it's a screwdriver with rum. I don't know why it's called Cowboy Roy, or even if that's what it's called anywhere else... I guess it's named after Roy Rogers. All I know is that it provides ample drunkenness along with plenty of vitamin C.
