An awkward silence.

I've done learnt a lesson about book writin'

I've learned that the phrase "an awkward silence" (or any derivative thereof) makes a very powerful impact by not existing at all.

For example...

Steve tried to explain what he meant about the phrase to the room full of literature experts. He tried to make a joke but muffed the punchline. There was an awkward silence. Everyone stared at him, making him glance down to see if his fly was open.

Can easily be changed to....

Wow... what a fucking miracle!
