ace in the hole
ace up his sleeve
against the grain
airing dirty laundry
all the tea in China
all thumbs
back from the dead
back in the saddle
back to the salt mine
bare bones
beat a dead horse
burn your bridges
skin of my teeth
cash cow
cat got your tongue?
chip off the old block
clean your clock
hell or high water
cooking with gas now
cool as a cucumber
an arm and a leg
cry over spilt milk
deep six (something)
deer in the headlights
dot i's and cross t'
drop in the bucket
drop of a hat
dumber than doornails
easy as 123
eat lead!
egg on his face
fell through cracks
like cats and gods
firing on all cylinders
fish out of water 
flat as a pancake
fly in the ointment
free as a bird
get a word in edgewise
get cleaned out
get over the hump
ghost of a chance
give an inch
good to the last drop
head over heels
hit pay dirt
hold your horses
horse race
hunker down
in your face
it's in the mail
jump down your throat
jump the gun
tip of the iceberg
close to his chest
kick butt (or ass) 
knockoff
knockout blow
back of the hand
know which side your
last but not least
cards on the table
lead balloon
leave no stone unturned
like night and day
needle in a haystack
love is blind
hand over fist
miss the boat
my brain is fried
nail-biter
nailed it
nail in the coffin
nice guys finish last
no pain, no gain
no skin off my nose
no strings attached
off kilter
the wrong foot
old as dirt
on the same page
out of gas
out of the woods
paint into corner
play with full deck
pound the pavement
pox on both houses
wool over the eyes
back burner
quick buck
rake in money 
rattle your cage
red carpet treatment
reinvent wheel
reopen old wound
right up your alley
rock the boat
Rome wasn't built in
rotten to the core
rub salt in the wound
run circles around
run rings around
same song and dance
trial balloon
shirt off your back
step on your toes
stitch in time
stop on a dime
sore thumb
sweep under the rug
swim against tide
test the waters
the 800-pound gorilla
blind leading blind
the cat's meow 
the rest is history
the whole enchilada
tilting at windmills
time on your hands
tongue-lashing
toot your own horn
to sugar coat
turn over anew leaf
under a microscope 
uphill battle
wasn't born yesterday
welcome to the club
born in a barn
hell freezes over
when pigs fly
where there's smoke 
wipe the slate clean
fine-tooth comb
won't (will) fly
works like a dog
yank your chain
take that to the bank
you lost me
you snooze, you loose
zip your lip
