Saying is one thing; doing is another
Scare the daylights out of someone
Screwed if you do, screwed if you don’t
Sell your birthright for a mess of pottage
Separate the sheep from the goats
Separate the wheat from the chaff
Show someone a clean pair of heels
Six of one and half-a-dozen of the other
Sixty-four-thousand-dollar-question
Sleep well- don’t let the bedbugs bite
Slower than molasses going uphill in January
Something nasty in the woodshed
Spare the rod and spoil the child
Speak softly and carry a big stick
Speak to the organ grinder not the monkey
Spirit is willing, but the flesh is weak
Spoil the ship for a ha’pworth of tar
Stand head and shoulders above
Stare down the barrel of a gun
Sticks and stones may break my bones, but names will never hurt me
Straw that broke the camel’s back
