Animals
Quit cold turkey
To give something up all at once
Call the shots
To make the decision
Apply some elbow grease
Put some extra effort into what you're doing
Call it a day
Stop working and go home
Cool as a cucumber
Calm and composed in a stressful situation
Smell a rat
To get a sense there is a problem with something
Game plan
Decide how things should be handled
By the skin of your teeth
Just barely
Get down to business
Get started on work, especially if you have limited time
Eager beaver
Someone who is eager or excited to do something
Zebras don't change their stripes
Don't expect anyone to be anything but who they are
Get the ball rolling
To begin or get started
Go belly up
Go out of business, lose everything
Back to the drawing board
To start over, get rid of a bad idea and start again
Beef up
To strengthen something
To be a fly on the wall
To wish to witness what is going on without everyone being aware that you are there
Drop the ball
To make a very basic mistake
Joined at the hip
People who seem to be together all the time
Learn the ropes
Learn how to do a particular job or task
Put a sock in it
Telling someone to stop talking
Straight from the horse's mouth
Get information straight from the most knowledgable source
Monday morning quarterback
Someone who tries to make a decision after the fact
No skin off my nose
You do not care, something won't affect you
Go the extra mile
To make an additional effort to achieve something
Like a long-tailed cat in a room full of rocking chairs
Someone who is very nervous
