The Pilot pulled out a .38 Revolver and set it on the top of the instrument panel. He said to the young Navigator; "Do you know what I use this for?"
The navigator swallowed and replied timidly "No, what do you use this for?"
"I use this on Navigators who get me lost" The pilot replied seriously.
The Navigator then pulled out a .45 and set it on the chart table.
"What the hell is that for" the Pilot asked incredulous.
"To be honest, Sir" the Navigator replied, "I'll know we're lost long before you do".
