I overheard someone say "It all boils down to the wire"From Gio:
Grasping at the last straw
Shoot fish in a barrel fist, ask questions later.A few cracking mixed metaphors from me
You can't walk on eggshells without cracking a few eggs.
You can't put all your eggs in one basket without cracking a few eggs.
Don't count your chickens before you've cracked a few eggs.
And Louis pointed me towards a scene from the movie Boondock Saints, which contains the following:
People in glass houses sink ships.
Don't cross the road if you can't get out of the kitchen.
