Moomin found a compass.
Moomin Papa asked him what he could possibly do with the compass.
Moomin looked at him strangely. 'Why, build a binnacle for it, to be sure! That's what people do with compasses!'
Moomin Papa was baffled.
'But what will you do with a compass in a binnacle?'' he asked, a little helplessly.
This was getting too much. The old troll had clearly lost his marbles.
'It's obvious!,' he burst out, 'I'll build a ship around the binnacle.'
With apologies to Tove Jansson,
and grateful thanks for a blessed childhood.
