Rachel Riley Manages (Just) To Keep A Straight Face After Being Exposed To An 'Erection' On 'Countdown'

Nobody could accuse Rachel Riley of not being a professional after she managed to resist giggling like a school kid when the word 'erection' errrm, popped up on 'Countdown'.

Rachel - who is in charge of the numbers and letters on the Channel 4 daytime show - kept it together (just) after being exposed to the word on this week's show.

But despite her innocent smile and apparent composure, Rachel later took to Twitter to share a pic of the moment she spelled out the word.

"Sometimes these words just pop up unexpectedly...gotta love the day job!" she joked.

And it wasn't long before fans of the show were tweeting their own gags…

It's not the first time the former 'Strictly' star has had to deal with a cheeky word on the quiz show.

Earlier this year, she had to cope with the word "orgasmed" not once but TWICE in two days.

A multiple orgasm, if you will.

Thank you, I'm here all week.
