Look at that sweet face. You can't deny that sweet reptilian face, can ya!?!

That's the theory behind what has been called the secret posture that can get you whatever you want, whenever you want. It's called...the "Kindly Brontosaurus".

How it works: Approach whomever you need something from -- let's say the airline employee. Give your name, make the request, and if they say no, simply smile and say, "Well, I'm sure we can find a way to work things out."

Then stand off to the side in their peripheral vision, lean forward a little, and clasp your hands in front of your stomach. Smile. Never stop looking at their face. Don't say anything unless they ask -- just nod enthusiastically whenever they speak to someone else.

Again, the theory is they'll eventually help you because you look so nice, friendly, respectful...but also crazy annoying and slightly creepy!

The body language expert named it the "kindly brontosaurus" because you're craning your neck and holding your arms like...you guessed it...a sweet brontosaurus.

Here's an (creepy) example:
