Love Island fans could not believe their eyes on Saturday's instalment of Unseen Bits.
Welsh hunk Liam Reardon was playing a game of Mr and Mrs with Millie Court against Toby Aromolaran and Chloe Burrows.
And while the couple were recently chosen by the public as one of the most intelligent couples in the villa, they may have just lost their title.
Millie revealed during the episode that she thought Madrid was a country, while Liam also confessed he did not know what "sibling" meant.
Meanwhile, Faye asked later on in the episode if being a doctor had anything to do with science.
"What's their sibling' names?" asked Toby, during the Mr and Mrs game.
