He Who Knows Everything

 The thunder egg does have a face. Two black rimmed eyes and a mouth that is laughing.

Also, white hair and a beard, which is what makes it a grandpa.

The eggs remain sceptical however.

Wouldn't our grandpa be a magpie?

No, says Terence. An egg would be your grandpa.

How do you know? ask the eggs.

He doesn't, says Gaius. An egg could well be considered your grandpa, but it would have to be the egg of a magpie.

My grandpa isn't, says Terence.

You don't have a grandpa, says Gaius.

I do. Grandpa Marx, says Terence. He knows everything.

I doubt it, says Gaius.

YOU don't know everything, says Terence.

Tell us about your grandpa, say the eggs.

He bought me a hat, says Terence.

Where is it? ask the eggs.

They would like to see it.

One of them looks sideways at the thunder egg.

Maybe it's listening.

I lost it, says Terence.

The frogs have tired of this talk about grandpas. Frogs don't have them. 

They are about to hop away.

Stop! says Gaius. Where are you going?

To see the Justice, Law and Order exhibition, says Shorty-Tartus. There's a small timber lockup that once held a bushranger.

Let's go! says Terence.

Can we stay here? ask the eggs.

Not really, says Gaius. How would that look?

You can come back this way and get us, say the eggs. We want to spend time with our grandpa.

I suppose there's no harm in it, says Gaius. All right, I'll leave you on top of the cabinet.

He places the eggs on the top of the cabinet, directly over their grandpa.

Grandpa thunder egg does not change his expression.

He does not need to.

The smile on his face is the smile of someone who might buy you a hat.

And then lecture you on the means of production.
