As happy as a clown
As happy as a lark
As happy as Larry
As hard as nails
As high as a kite
As hoarse as a crow
As hot as hell
As hungry as a bear
As hungry as a wolf
As innocent as a lamb
As keen as mustard
As large as life
As light as a feather
As light as air
As likely as not
As lowly as a worm
As mad as a hatter
As mad as a hornet
As mad as the march hare
As merry as a cricket
As modest as a maiden
As much use as a yard of pump water
As naked as a baby
As neat as a pin
As nutty as a fruitcake
As obstinate as a mule
As old as the hills
As pale as death
As patient as Job
As plain as day
As pleased as Punch
As poor as a church mouse
As poor as dirt
As pretty as a picture
As proud as a peacock
As pure as snow
As pure as the driven snow
As quick as a wink
As quick as lightning
As quick as silver
As right as rain
As safe as houses
As scarce as hen's teeth
As sensitive as a flower
As sharp as a needle
As sharp as a razor
As sick as a dog
As sick as a parrt
As silent as the dead
As silly as a goose
As slippery as an eel
As slow as molasses
As slow as a snail
As slow as a tortoise
As smooth as silk
As snug as a bug in a rug
As sober as a judge
As soft as a baby's bottom
As solid as a rock
As solid as the ground we stand on
As sound as a bell
As sour as vinegar
As steady as a rock
As sticky as jam
As stiff as a board
As still as death
As straight as an arrow
As strong as an ox
As stubborn as a mule
As sturdy as an oak
As sure as death and taxes
As sweet as honey
As tall as a giraffe
As tight as a drum
As thick as a brick
As thin as a rake
As thin as a toothpick
As timid as a rabbit
As tough as leather
As tough as nails
As tough as old boots
As tricky as a box of monkeys
As welcome as a skunk at a lawn party
As white as a ghost
As white as a sheet
As white as snow
As wise as Solomon
As wise as an owl
