Magic

"Read this to yourself. Read it silently.
Don't move your lips. Don't make a sound.
Listen to yourself. Listen without hearing anything.
What a wonderfully weird thing, huh?

NOW MAKE THIS PART LOUD!
SCREAM IT IN YOUR MIND!
DROWN EVERYTHING OUT!
Now, hear a whisper. A tiny whisper.

Now, read this line with the best crotchety-old man voice:
'Hello there sonny. Does your town have a post office?'
Awesome! Who was that? Whose voice was that? 
It sure wasn't yours!

How do you do that? 
How?! 
Must be magic."

-Bo Burnham

I think this speaks for itself to be honest.
