When I picked up the phone, I got the operator. He asked with whom I wanted to speak, and I said I'd like a local Chinese restaurant that delivered.
The operator said the phone could only be used to communicate with Platonic polychorons. "You know, like Platonic solids, but in four spatial dimensions."
"But isn't the fourth dimension Time?" I asked. I knew that wasn't what he meant, but I wanted to annoy him, since I really wanted Chinese food.
He sighed and said, "No. Would you like to speak with a hypercube? It has eight equaly-sized cubes for its sides, you know."
"Is the hypercube nice?" I asked, but I hung up and walked away before the operator could answer.
Such is the Way of the Desert.
