How to sound smart in your TEDx Talk

I have heard that this talk is brought to you by two TED staffers, who have watched a LOT of TED Talks. I want to know that two TED staffers, because I think that he might be Sebastian Wernicke. Right? I'm sorry that Sebastian Wernicke's TEDTalk: Lies, damned lies and statistics (about TEDTalks) is more interesting than this. hahaha:D

Will Stephen: How to sound smart in your TEDx Talk
Summary
If you don't prepare anything or you don't have any idea at today's conference, by using this way, you will look smart.
First, you should speak out about just title.
Make a lot of hand gestures, talk about an anecdote and ask them some questions. It's better for you to adjust your glasses, thus it's good to wear it at some stage, even if you don't wear it. 
Don't forget to use pictures, graphs, many numbers and say and line difficult words as far as you know with confidence.
At the end, return to the beginning, and say "I'm going to stop talking, thank you."  It might be good even just looking confident.
