throw A to the wolves

when it comes to a pinch

spring chicken

have had one's day

long in the tooth

kick oneself

on the blink

whiz kid

leave A in the dust

boggle the mind

line one's pockets

whoop it up

keep one's nose clean

with half a heart

a chip off the old block

lose sleep over

drown one's sorrows

jump down A's throat

with one's tail between one's legs

in mint condition

pick A's brain

within an inch of

cut each other's throats

green with envy

within spitting distance

hush money

in no shape

clear one's name

have a scrape

pull a rabbit out of the hat

without further ado

rub up

worth one's weight in gold

come to grief

sound as a bell

make oneself scarce

get off the mark

would not put it past A to do

sit up and take notice

feel A in one's bones
