You're twice the woman than she is

Fool me once shame on you, fool me twice shame on me 

You should think twice before doing that

You don't look well

Looks can be deceiving 

He looked like death warmed over

You can look, but don't touch 

Look at it this way.....

Look before you leap

Don't leap from the frying pan into the fire!

If you play with fire, you get burnt

Should my ears be burning 

You've been burning the candle at both ends

This money is burning a hole in my pocket 

I had to burn the midnight oil

You don't want to burn bridges 

He's got money to burn

Aww he gave me a Chinese burn 

It's hot enough to burn a polar bears butt

Burn baby burn - disco inferno ?

It will burn itself out

I'm doing a slow burn here

I got my fingers burnt

He's going to crash and burn

Are you going to burn me on this deal?
