Yeah, I do think some are pretty funny (eg tan lines) and some are not so terrible, but I honestly think she took them incredibly seriously and wasn’t trying to make her colleagues laugh as much as just ….. put out an air of “look how personable and authentic I am”. She also lamented that other people’s OOOs were “rigid” and why couldn’t people have fun?! Which again, sounds not so bad but was someone who would regularly ask prying inappropriate personal questions, so it came across less like “let’s loosen up” and more like “why won’t people tell me the specifics of why they’re off today, because I deserve to know”.
They weren’t saying that’s the entirety of their message, just that that’s the phrase they’re using instead of ‘out of office’

It’s wise to check they aren’t though. A colleague once had an out of office from an academic that simply said ‘on fieldwork’. Just those two words.
No one thinks much about cybersecurity while traveling. However, email security company Tessian warns the out of office message actually plays right into the hands of threat actors and cybercriminals. It’s a social engineering attack vector that no one thinks about. The out of office message is ubiquitous and handy. But if it includes any personal information at all — such as attending a funeral or going out of the country — attackers have all the information they need to impersonate the person who is out of the office, without the attacker having to do any real work.
