SAY CHEESE!

Here's an interesting test for you. See if you can spot the fake smiles. For some reason, people are not very good at discerning between fake and genuine smiles. I took the test and guessed "fake" for every single one. They all looked fishy to me. They are not all fake, I can assure you - so do your best to pick out the folks who forced a smile from those who smiled because they felt good about something.
