A four horse day
A four horse day is when everything goes wrong, and you swear you'll never work again, even if you have to ride four horses to escape.
My day started with a four horse day, and I didn't even have coffee yet.
I said, 'This is the worst four horse day ever!' My boss said, 'You're just tired.' I said, 'No, I'm furious.'
Today was a four horse day, and I even had to fight my printer.
