This is usually a performance piece, presented as a piece of stand-up or a joke. It falls into a category of surreal humour and wordplay that works best when said aloud.
The Opening of the Queernomicon
It had been an odd day.
Children in the neighbourhood had begun
exploring their gender, and become
increasingly less visible until
no one could identify them at all.
That night, little Timmy lay in bed
and said, “Mummy, I’m scared.
I think there’s an asexual in my room.”
His mum laughed and said,
“Don’t be silly. Everyone knows
asexuals don’t exist.”
She was wrong.
