Make an Orange Julius

So what is an Orange Julius? I happened upon this site, which has some neat copycat recipes.
Want to try one?

6 oz frozen orange juice concentrate
1 cup milk, can be low-fat
1 cup water
1/4 cup granulated sugar
1 teaspoon vanilla extract
8 ice cubes
Put all ingredients in a blender. Blend adding ice cubes one at a time until mixture is smooth.
BTW, I don't even know if Paul even liked these, it just popped in my brain.
