a dime a dozen

blow hot and cold

catch one's death

pull a rabbit out of the hat

get off A's case

a feather in one's cap

in drag

the upper crust

to the gills

a flash in the pan

American as apple pie

blow one's top

have a scrape

a fly on the wall

Big Brother

hope against hope

a happy medium

hit a raw nerve

in deep water

to cap it all

in the sticks

raise an eyebrow

make a bundle

a hill of beans

old chestnut

on approval

a hundred and one

strike oil

give the game away

cast one's mind back to

a knight in shining armor

paper tiger

beat the clock

a man of the people

keep up appearances

break the mold

cut the mustard

take a shine to

a mile off

make a break for it
