Bernard starts yodeling from the conning tower, and I have to pass the message on to the comms officer, who yodels it through the Yodecoder, yodeling the plaintext to the kaleun.
Then we realise that it's double-enyodeled for extra throat-wobble security, and we are treated to the sounds of the old man quietly yodeling to himself in his cabin.
