Obviously I know this is a joke based on its etymology, so lol.
But just to be serious for a moment (a small pet peve of mine). Technically it does **not** mean "set apart". Holy means the following (its definition):
dedicated or consecrated to God or a religious purpose; sacred.
Now if you go back 2000 years ago to long before the word "holy" even existed there was a word in a different language (hebrew and greek) that meant "set apart". That word, along with its definition, over many generations, evolved into the modern word holy with its current definition. But the etymology of a word is **not** what the word **means**, that is an incorrect interpritation of a word's etymology (and a pet peve of mine as I hear that often).
@freemo What I kept hearing with your original joke were the countless Batman sitcom episodes I watched as a child, and Robin would exclaim: "Holy ____ Batman!" Fill in the blank with some especially ludicrous aspect of the story.
