If you feed the monster who lives under your bed, it will grow bigger until it doesn't fit anymore. Then your bed will be topsy turvy.
When your bed is topsy turvy, you won't sleep well.
When your bed is topsy turvy, you won't sleep well.
When you don't sleep well, you will become grumpy.
When you're grumpy, you will be less polite to the monster, and it will become grumpy as well.
When the monster is grumpy, it will eat you out of spite.
But at least monster stomachs have free WiFi.
And that's all that really matters in the end, right?
