As it's nearly the weekend, here's a fairly comprehensive list of all the times newsreaders went off on one, lost it or just lost the plot.
1. Simon McCoy – Royal Baby joy
There's nothing like a royal baby announcement to get BBC News' Simon McCoy in the mood.
On hearing the announcement of a third baby for Wills and Kate, he deadpanned: "I'm not sure how much news this is, but it's April. Clear your diaries, get the time booked off – because that's what I'm doing."
2. Jeremy Paxman - Jeremy Snarkman
Do not make Jeremy Paxman do anything other than a) interview people or b) talk about the news.
Because if you ask him to do anything else (including the weather) he won't just be unhappy about it, he'll go off-script and be so witheringly sarcastic you'll probably want to switch off and sit in a dark room for a bit.
3. Natasha Exelby - inappropriate giggles
This clip shows how the news can go really wrong when you go off-script. Presenter Natasha Exelby has to shift between some unplanned flirtatious banter with a guest, straight into some of the most serious news stories of the day.
Unfortunately, because of the off-script stuff, she gets the giggles at basically the most inopportune moments possible.
4. Dan Harris - panic
When ABC anchor Dan Harris had an on-air panic attack, he had to go off script to get out of his segment earlier than expected.
His (extremely professional) colleagues covered, and a casual viewer might not have realised that something had gone wrong.
So, it's admirable that Harris didn't just 'fess up to what happened, he used it as an opportunity to teach people about the process of experiencing a panic attack. Powerful stuff.
5. Tom Donkin - running around
Not so much off-script as off-camera, poor old Tom Donkin makes an unexpected journey, running around the studio until he finally finds himself in the spot he's supposed to be in.
Unlike some on this list, he doesn't make a gag of his gaff, presumably hoping that the BBC news set has a section of the floor which will swallow him whole after he's finished. Poor Donkin.
6. Martine Croxall - off-camera chill
Contrast Donkin with Martine Croxall, who not only styles out the mistake by calmly sliding into the chair she's supposed to be in, she does it while commentating on the error, while finding time to squeeze a joke about the situation into the script. Bravo, Martine.
7. Carol Walker - casual hairbrush
We can't really blame Carol Walker for this one, especially when the screen clearly shows the camera-team cut to her a full four minutes early, so when she said it's nine o'clock, it was the laws of time that caused her to go off script. Still, that handbag on the desk is pretty funny.
Walker seemed to find the funny side on Twitter, even if, in the moment, she does seem super serious.
8. John Craig - Dropping an f-bong
When Sky News' John Craig was interrupted by the bonging of Big Ben while he was trying to do his job, he did what many of us might – he swore.
However, unlike many of us, he was on camera at the time, and his frustration was broadcast to the entire nation.
But it was followed by an immediate apology so we're sure it's fine and no-one wrote in to complain.
9. Jonathan Charles - punctuation is your friend
Okay, technically he didn't go off script. In fact, he was rigidly ON script.
When you pay attention to the actual words that Jonathan Charles immediately goes into after introducing himself, it sounds like a pretty dark story. Which is why Charles should have paid attention to the moment in the script where it tells him to pause between sentences. Because as a run-on statement, it's accidentally hilarious.
