Somewhere out there....
Sonar operator: "Comrade Kapitan, sonar contact bearing 067."
Kapitan: " Can you identify it?"
Sonar operator grimaces for a few seconds: "No sir, whales maybe?"
Kapitan takes the earphone for a few moments and listens...
[
oh yeah, oh yeah, faster, faster FASTER, cowabungaaaaa!] silence...
Kapitan: "It's not a whale"
