US CRUISER JOKE
A US cruiser was patrolling when the captain received a radio message, something like:
"Hey could you change your route please? You're going straight to bump into me"
The US replied "no, YOU change your route".
And that "not me, you" discussion lasted for a while when finally, the US captain started to threaten the other guy saying he was commanding a powerful warship. Then he heard the following reply:
"I cannot change my route coz I'm in a lighthouse!"...
