Subject: “I am currently out of the office and probably chilling on the beach. Enjoy your work week.”

That’s it. That’s all. Simple and to the point, this message will let people know that you can’t respond to messages.

That said, be careful with messages that are this curt. Make sure you’re familiar enough with your audience — and your boss, for that matter — to know that this sort of out-of-office message will be met with a snicker, and not with annoyance.
