A Light in the Distance

A captain notices a light in the distance, on a collision course with his ship.

He turns on his signal lamp and sends, "Change your course, 10 degrees west."

The light signals back, "Change yours,10 degrees east."

The captain gets a little annoyed.  He signals, "I’m a US Navy captain.  You must change your course, sir."

The light signals back, "I’m a Seaman First Class.  You must change your course, sir."

Now the captain is mad.  He signals, "I’m an aircraft carrier.  I’m not changing my course."

The light signals back a final message: "I’m a lighthouse.  Your call."
