#41: A Deceptive Smile
You might be one of those people who can’t help but nervously laugh or smile when they lie. It happens to the best of us. If you want to be truly diabolical and borderline evil, try this hack. Simply smile every time you tell the truth. Then, when you feel the urge to smile or laugh through a lie, people will be more likely to believe you.

This hack is definitely for those who don’t mind playing the long game. It also might be kind of weird if you’ve never smiled that much before. Your friends and family might be concerned that you’re suddenly smiling left and right like a maniac. Actually, now that we think about it, this hack doesn’t work as well as some people think it does.
