RACHEL Riley was left red-faced by the climax to one word game in today's Countdown as she spelled out "orgasm".
The show's numbers wiz struggled to keep a straight face as comedian Shappi Khorsandi came up with the eight-letter word.
Looking vibrant in a bright red dress, Rachel smiled knowingly beside the collection of consonants and vowels.
Just days ago Rachel was even more bashful as "blowie" appeared on the board.
Shappi was once again the one to offer up the rude word on the Channel 4 show, insisting that it was a kind of fly.
Her six-letter answer raised eyebrows around the studio but Rachel managed to stop herself from giggling as she put the word on the board,
"It’s a fly," Shappi said.
"A kind of fly."
It was up to Susie Dent on Dictionary Corner to confirm the comedian was right and a blowie is the informal term for a blowfly.
Clever Shappi one-upped the other two contestants who only came up with five-letter words including ‘bowel’ and ‘whale’.
Last year Countdown was forced to blur out the word “w***ers” after it appeared on the board – leaving Rachel in hysterics.
