Tropes R Us.

 You will see a real blue moon when pigs fly.

And then it will rain cats and dogs, because you have bats in your belfry.

Out of office experience.

 A woman's work is never done.

He gives more homework than a teacher.

Talk the talk.

 Who would dare to complain?

Besides present company.

Children, what's that sound??

 There's somethin' happenin' here

But what it is ain't exactly clear

 More like what it was.

Me, Myself and I.

 You and what army of one?

 The majority of one.

The good old days.

Nostalgia for the simpler times.

From bad to worse.

There's an app for that.

 There will be plenty of headaches no matter what.

There's a pill for anxiety.
