I saw this on a board dedicated to my greatest personal vice, railroads big and small.
You know it’s going to be a bad day when you get out of bed, put your shoes on, and they’re still warm.
You know you’re having a bad day when people keep doing this to you.
You know you are having a bad day when you wake up early in the morning to a wretched sound and while searching for sound step in dog puke.
You know it’s gonna be a bad day when you wake up on the pavement
You know it’s gonna be a bad day when you have to get up so early that your dog is not excited about eating breakfast and decides to go back to sleep, lucky bitch.
you know it’s gonna be a bad day when you get in a fight with your wife before the first cup of coffee 
Well, after seeing Necromancer’s link, I’m no longer having a bad day.
Thanks!
You know it’s going to be a bad day when you wake up, swing your legs out of bed, and put your foot down on a wasp, which proceeds to sting you in the arch of your sole.
Actually happened to me.
Oooh, I used to have a poster on this…
You know you’re having a bad day when…
You dream that you just ate the world’s biggest marshmallow, and you wake up to find that your pillow is missing.
You know its going to be a bad day when you dream you’re eating a giant marshmallow and when you wake up your pillow is gone.
Great minds think alike, NurseCarmen!
…so do the little ones.
All in one day…
I discovered I’d been running the wrong commercial for an advertiser all month…
I gave myself one HELL of a folder cut…
My belt fell into the toilet while I was going to the bathroom and I peed on it.
It was a cloth belt, so needless to say I was sans belt for the rest of the day until I could toss that baby into the washer.
Or better yet, when you hear the retching noise, open your eyes and see the dog sitting on your chest. Actually happened to me once…
…and then you remember that you don’t even have a dog.
