Conundrum Existence

What the dickens is knot theory? asks Vello. 

I know not, says David. 

Very funny, says Vello. Sweezus, do you know?

Yeah, says Sweezus. It's a thing in mathematics. Like, about closed loops and stuff.

So not proper knots then, says Vello. 

Not like knots in real life, says Sweezus. Theoretical knots. There's also the unknot, which is a closed loop without a knot in it.

A ring! says Vello. Why not just call it a ring?

Or a headband, says Belle.

Or underpants, says Terence.

It can't be underpants, says Baby Pierre. The closed loop is at the top but there's two open loops at the bottom.

You never wear underpants, says Terence.

It can be a squiggle, says Sweezus. 

You seem to have learned a great deal about mathematics, says Vello.

From Sartre, says Sweezus. He was into it. He reckoned we humans are no different from a donut. 

He would, says Vello. Didn't he also say that human existence is a conundrum whereby each of us exists in a condition of nothingness?

Then he contradicted himself, says David. Viz, the donut.

We'd been eating a shitload of oysters, and drinking French wine, says Sweezus. He may've been tipsy.

That reminds me, says Vello. Shouldn't we be heading to Gluttony to set up the stage?

We should, says David. Do we know how we're going to get the two tables and the cardboard mast and the costumes and the coconut and the box of seeds to the venue?

Belle? asks Vello. 

It's all organised, says Belle. I'm picking up the Move-it-Yourself van in fifteen minutes.

What would I do without you, dear? says Vello.

Exist in a conundrum, says Belle.
