Smile and Say Cheese/Marmoset/Aubergine!

In English we don't really have too much need to question the phrase that we use to encourage folks to smile when we are taking a photo:

Say Cheese!

This is probably because we also have the associations with "cheesy" and our smiles.  And a cheesy smile makes for a great photo.

In reality, though, the two are most likely not linked, and cheese is just a word with an elongated vowel that makes us smile as we say it.

There are some great foreign language examples in this Wikipedia entry :

A couple of my favourites, though - checked via other sources - are as follows:

French: Marmoset

ouistiti

Chinese: Aubergine

茄子

qiézi (sounds like cheese)
