Riko, an official once presented a doubt to Nansen, about a goose in the bottle.

He said, "Master when a man puts a gosling into a bottle and feeds it until it is fully grown, how can he take the bird out, without killing it or breaking the bottle"

The master made loud clap with his hands.

Riko immediately said, "Yes master" with a start.

"See" said Nansen, "The goose it out!"
