Jen and I stumbled upon a test this morning while we were prepping for our show.  Take your index finger and draw a capital 'Q' on your forehead.  If you drew the 'Q' with the bottom tail pointing left, so someone looking at you would read it normally, that means your aware of how people perceive you, and YOU'RE a GOOD liar.  Now if you drew the 'Q' with the bottom tail on the right side, so it would be backwards to someone looking at you, that means YOU'RE more introverted and YOU'RE a BAD liar.

All 3 of us on the show today were very BAD liars lol.  Give it a shot tonight at home with your significant other or around the office.
