Channel 4 Countdown's Rachel Riley just about managed to contain her giggles after a contestant spelt out a rather cheeky word.
But presenter Nick Hewer wasn't quite as composed and even asked contestant Pam to repeat herself to check he had heard correctly.
He then repeated the word again, before Susie Dent in the dictionary corner broke the awkward moment by saying "very good".
The word in question was 'fetish', which ended up leaving the whole team muffling their giggles.
When the time came for Rachel, 34, to spell out the word she almost gave away a smile, before she turns back to face the camera straight-faced.
Only last week guest star Rory Bremner pointed out the word 'screwing' during the letters game, whilst other contestants Val and Tim suggested 'creasing' and 'swearing'.
Suzy, who was siting beside Rory, was as calm as ever as she said: "Yes, that’s there for eight."
Before adding: "You can also be a wincer".
This was a bit too much for Rachel and she was seen with a shocked expression, clearly holding back her laughter.
In another episode, contestant Tony asked Rachel to card a few more consonants and vowels, starting with three vowels to begin with.
The letters E, U, and I came up, before Rachel added the consonants, C, N and T.
And it wasn't long before it was clear Rachel had noticed a rude word hidden between the mixed up letters.
The entire studio went quiet, but nobody pointed the word out.
The show had been pre-recorded as we noticed Rachel was still pregnant with her first child, Maven Aria, at the time of filming.
She was wearing a red floral tea dress, and could be seen cradling her bump as the contestants gave their suggestions.
Rachel returned back to work in February, posting a picture to her Instagram with the caption: "First block back at work done and dusted and I can still sum post baby… phew!" after giving birth in December of last year.
