From #lounge and other logs:

<aloril>  So Cool!!!
<aloril>  ----------
<aloril>  A young and foolish pilot wanted to sound cool and show who was 
<aloril>  boss on the aviation frequencies. So, this was his first time 
<aloril>  approaching a field during the nighttime. Instead of making any 
<aloril>  official requests to the tower, he said: "Guess who?"
<aloril>  The controller switched the field lights off and replied: "Guess
<aloril>  where!"
<TheedMan> LOL
<TheedMan> remembers a conversation from a navy warship asking the
           ship ahead of it to turn aside, and them them by (this was in the fog)
<TheedMan> the navy ship eventaully, identifies who they are, 
           and the other "ship" responds, we are a lighthouse...
<malcolm> "This is the USS <??>, an American Aircraft Carrier, and
          we *demand* that you make way!
<malcolm> "This is a lighthouse.  Your call."
<TheedMan> yeah, what he said             

<dcyoung> "I'm a lighthouse, sir.  Your call."
