THE SCOTTISH PLAY
Going to see MacBeth this weekend, I couldn't help but notice all the turns of phrase and common references the play has added to even today's everyday conversation.
But, I think there can still be more:

From now on, instead of saying,
Gimme a minute to get ready, I'm going to say:
"Let's briefly put on manly readiness"

Instead of saying,
Lighten up or Don't be such a killjoy, I'm going to say:
"You have displaced the mirth"

And instead of saying, Can you wait a minute, I'm gonna say,
"Avaunt! and quit my sight! let the earth hide thee."
