Snake oil
A fake and worthless medicine
Play second fiddle
To be the second choice
Keep at arm's length
To stay away from someone
One hit wonder
Someone who does something great only one time
A penny pincher
A cheap person
An apple a day keeps the doctor away
Advice for a healthy diet that keeps you well
Face the music
Deal with a problem
Keep your chin up
To try to stay positive
Back to square one
To start over
Go Dutch
To split the bill
A recipe for disaster
Habits that will cause poor health
Sing a different tune
To be unique
Like pulling teeth
To make something very difficult
To be of two minds
To be undecided about something
Pay through the nose
To pay too much for something
Step up to the plate
To finally address a problem
Blow your own horn
To brag
Sweet tooth
Loving candy
Kill two birds with one stone
To take care of two things at once
Penny wise and pound foolish
To be cheap about buying something and end up paying more later
A wake-up call
Realizing you need to change your ways
It rings a bell
Something that seems familiar
Give them the cold shoulder
To ignore someone
Six in one and half a dozen in the other
When two things are the same
Chump change
An insignificant amount of money
