The Old Improbable Island Wiki

Yes it does there is. This is what is commonly referred to as a "lie".

While the existence of an actual Spoon on Improbable Island is a matter of much debate, the existence of the Clan, 'There is no Spoon' cannot be denied. Founded by the husband and wife team of Arouette and Daychilde, <SPOON> is one of the most successful clans of Season One in terms of Role Playing, Hall of Fame Records, and general Island style fun.

Also there are rumours that several members of the clan are fond of Lie Cake.

This may have led to the strange utterance of a lower level contestant. “there is no Spoon, and the cake is a lie. but that wont stop me from using my No Spoon¹⁾ to eat my piece of lie Cake.”
