A bear of very little brain
A bird in the hand is worth two in the bush
A chip on his shoulder
A foot in both campss
A healthy mind in a healthy body
A man after my own heart
Able bodied
Above my head
Absence makes the heart grow fonder
Affair of the heart
After your own heart
Air head
All I want for Christmas is my two front teeth
All mouth and trousers
All my eye and Betty Martin
Always have your nose in a book
Ample bosom
An albatross round his neck
An army marches on its stomach
An tooth
Ankle biter
Ankle deep
Anybody's guess
Arm candy
arm
Armed to the teeth
Arms and the Man
Arse about face
Arse over tit
As busy as a one legged arse kicker
As cold as a well digger's arse
As crooked as a dog's hind leg
As cute as a bug's ear
As far as the eye can see
As fine as frog's hair
As long as my arm
As mad as a bear with a sore head
As many chins as a Chinese phone book
As plain as the nose on your face
As scarce as hen's teeth
As stiff as a poker
As tight as a duck's arse
As useless as tits on a boar
Athlete's foot
Babe in arms
Bad hair day
Banging your head against a brick wall
Bare one's teeth
Be it on your head
Be still my quiet heart
Bear arms
Beauty is in the eye of the beholder
Bend your ear
Bend your elbow
Better than a poke in the eye with a sharp stick
Bird's eye view
Bite someone's head off
Bite the hand that feeds you
Bite your hand off
Bite your head off
Bite your lip
Bite your tongue
Biting the hand that feeds IT (The Register)
Bleeding heart liberal
Body and soul
Body bag
Body blow
Body-building
Body heat
Body language
Body of evidence
Body of opinion
Body politic
Body popping
Body snatcher
Body surfing
Bone head
Born with a silver spoon in his mouth
Bosom buddies
Bosom pals
Bound foot
Bow the knee
Brain dead
Brain drain
Brain dump
Brain fart
Brain-teaser
Brain wave
Break a leg
Break your heart
Bring to a head
Brothers in arms
Bury your head in the sand
Business at hand
Busy as a one legged arse kicker
Butt head
Butter wouldn't melt in her mouth
Butterflies in my stomach
Button your lip
By heart
By the hairs on my chinny chin chin, I'll blow your house down
By the scruff of your neck
By the skin of your teeth
By the sweat of his brow
Call to arms
Can't make head or tail of it
Can't see beyond the end of your nose
Cap in hand
Case the joint
Cast an eye over
Catch your eye
Caught with his hand in the cookie jar
Caught with your hand in the till
Cauliflower ear
Chance your arm
Change of heart
Cheek by jowl
Chin wag
Clear your throat
Cock a leg
Cold as a well digger's arse
Cold hands warm heart
Come the three corners of the world in arms
Condemned out of hand
Contemplate my navel
Cost an leg
Couldn't make head or tail of it
Crooked as a dog's hind leg
Cross my heart and hope to die
Cross my palm with silver
Cry your heart out
Cut off your nose to spite your face
Cut throat competition
Cut your teeth
Cute as a bug's ear
