A Total Eclipse of the Shopping Cart

Eggs? No, no, no, not the right shape.

Clementines? Closer, but the colour is way off.

Large tortillas? Better, but think much bigger than that.

Io? No, too big. That's Jupiter's.

Pluto? Surprisingly, that's a third too small.

So what is it then? Look up, really look, what do you see when the light is snuffed out? What's round and nearby and hangs in the night sky?

Eco lightbulbs? No! It's the bloody moon! The sun is eclipsed by the moon!
