Lister and Holly in “Thanks for the Memory”

Lister

And for this very special occasion I have baked - a cake.

What's that then?

Lister

It's in the shape of a spanner, Holly, cos he was a technician.

Well, that's very apt, that is. If he'd been a postman you'd have baked it in the shape of an envelope, I suppose?

Lister

Yeah!

Gordon Bennett, it's lucky he's not a gynaecologist.
