Fifteen cups & a poem

You’ve been tricked!
There are 15 poems in this cup
If you find less
Then the cup should be broken
If you find more
That’s all that matters
If you find none
Well,
maybe someone has picked
But there are 15 poems in this cup
If they’re still here
All the cups should be taken
At the end of this poem
There should be no cups
That’s all.
