Things that come as a set are meant to stay together.
Removing any piece of that set will likely make the set look strange—if not outright hilarious.
Let's take, for example, this set of ice cream bowls.
Now as we all know, the saying is "I scream, you scream, we all scream for ice cream!"
But since we are missing a bowl, all we get is:
"I scream. You scream. We all scream."
Also the deadly smiles of the children on the bowl?
They simply do nothing to take away from the creepiness of the sentiment.
This is not the only copy of the bowls that exist, so others have been offering their view of the complete set and similar bowls.
Each set, regardless of text upon it, comes with the soulless, scary, chalk-drawing children who can only smile and stare.
The probability of this set of bowls being from a horror movie is ALMOST zero, nonetheless, they will possibly haunt our nightmares for decades to come.
I scream.
You scream.
We all scream.
