There is another scenario where one of the characters will approach you with some "breadstuffs" he picked from a tree. The breadstuff looks a great deal like spagetti in the picture. This is a reference to a well-known April Fool's joke broadcast by the BBC on April 1, 1957 in which "Swiss" people were shown harvesting spagetti from trees. The BBC broadcast is documented in detail at the following site: http://www.snopes.com/holidays/april/aprlfool.htm#bbc.
There is a scenario in the game where you will come acrosss a character referred to as "Piltdown Man". As every anthropology student knows, Piltdown Man is one of the most well-known fossilized human remains hoaxes in history. True to form, Lost Tribe's Piltdown Man will swindle your tribe if given the chance, and when he does, the other members of the tribe will say that it was obvious to them that he was a phony.
