Viewers were left gasping when a very rude word was spelt out in Countdown.

Normally the show is quite pleasant with contestants spelling words and working out sums.

But every now and again, something hilarious happens that has the whole world talking!

The show's star Rachel Riley was taking up various letters and her face slowly turned red when she noticed what word was being spelt.

Before she knew it, the world "gobsh*te" was up on her board.

Fans were shocked by the surprise word but absolutely loved it!

The show rarely has these moments but when they do, viewers go crazy.

One of the most talked about things online about the blunder is that the word is a very popular phrase from hit Channel 4 show, Father Ted.

The show has a huge cult following and it was Father Jack who was fond of calling others "gobsh*te."

To be fair, we Irish are fond of the word!
