Yes! I remember reading here the phrase: the default mode of clever is asshole. Meaning when trying to be clever backfires, you end up just looking like an asshole. I’ve given up the need to get laughs at my clever sense of humor while at work. I really hope that out of office message is for internal emails only, because the risk of this landing badly is too high.
I wish I’d copied it, but once a co-worker in sales had an out of office that was long and rambling and talked about how she and her family were “going to visit Mickey.” I didn’t know what to make of it, especially since it could go to prospective clients.

Except since we usually have a strict 2 GB inbox limit, that usually lasts about 2-3 months at best and then nobody can send you anything at all so it works out. (In-organization they’ll still see the OOO when they put you into the address bar, so it works out that it’s not TOO much to delete when you return.
I can see why you’d have a negative reaction to it–that’s how I felt the first several times I heard about these kinds of emails–but I don’t think it’s actually rude (unless they’re saying “if I get emails from Ali G, I’m deleting them”). The wording of the email can be rude, but the general concept of this kind of email isn’t.
