Alex Jones cut her finger on The One Show - but even though blood spurted everywhere, she was unable to get help.
The Welsh presenter told viewers: "I gave myself a paper cut, and I've just got blood everywhere."
But social distancing rules meant the crew couldn't come to her assistance.
She looked quite worried when it happened, as no one was allowed near.
Holding her hands out , she said: "It's just a paper cut - but I haven't got a tissue."
As Watchdog correspondent Matt Allwright explained, co-presenter Alex Scott would have to break strict government guidelines to go to her aid.
He told her: "We can't help you."
But eventually, she tracked down a tissue.
"Don't worry it's fine. There's one here," Alex said.
She then started dabbing the blood while, like a pro, reading out the next link.
The One Show started social distancing on screen after coming under fire from viewers in March.
Alex and Irish comic Patrick Kielty ended up on opposite sofas.
That was after getting complaints about how close they had been sitting.
She also faced criticism when presenting with what looked suspiciously like a new haircut.
However, after fans raised the issue on social media, Alex put them straight.
"Just to clarify, no haircut has happened since the end of Feb, before lockdown (which was a tiny trim).
"I’m sort of pleased that you think I have had it cut though because it’s a right mess!!!!!" She said.
The One Show is filmed with just the hosts and a cameraperson in the studio to make sure social distancing rules are followed.
Presenters have to sit two metres apart.
