Things you CANNOT do

-look daggers

I can pull my socks up, but I can't

- get my knickers in a twist
- eat my hat
- make a mountain out of a molehill

Beat yourself up.
Have your jaw on the floor with shock.
Meet yourself coming back.
Have your head up your arse physically impossible I would think
Have green fingers.
Melt down.

My mother used to tell us to haud your wheesht when she wanted us to stop talking.

Put the cart before the horse.

Sorry to be literal, but I can haud ma wheest. I can also think of quite a lot of things, gateposts for instance that I could drive a horse and cart through and lots of others that can be burnt to a cinder.

I am really enjoying this thread.

Anyone able to jump out of their skin, or over the moon for joy?

Burnt to a cinder

Turn in the grave

Sit down and sit up! As teachers used to say to me.

Do anything ten or even nineteen to the dozen!

Shiver your timbers

"Eat your dinner up" - surely it has to go down?
"Button your lip" - a bit painful I think?
"Wear your heart on your sleeve" - also a bit painful!

Bob's your uncle.. Unless you just happen to have an uncle called Bob.

A watched kettle never boils.

Your eyes were bigger than your belly.

(When you put too much food on your plate and couldn’t eat it all)

Run after one and catch two.

My mum used to tell us to do this if we were bored.

Eat your heart out

For Scots- hud yer wheesht. I am not too sure about the spelling of the last word.

For others- hold your breath

I was beside myself.

drive a coach and horses through it;

been to hell and back;

spitting tacks/ feathers;

eat crusts to make your hair curl

Eat until you pop.

Make a silk purse out of a sow's ear.

Turn a blind eye.
Shut your mouth and eat your dinner.

As you can see, I'm getting carried away with this. Love this post Phoenix.

(noise related) you'll wake the dead.

Work your arse off.

Cut the atmosphere with a knife
