The Navigator

The pilot was sitting in his seat and pulled out a .38 revolver. He placed it on top of the instrument panel, then asked the new navigator, "Do you know what I use this for?"

The navigator replied timidly, "No, what's it for?"

The pilot responded, "I use this on navigators who get me lost!"

The navigator proceeded to pull out a .45 and place it on his chart table.

The pilot asked, "What's that for?"

"To be honest sir," the navigator replied, "I'll know we're lost before you will."
