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 navigator, "Do you know what I use this for?" The navigator replied, "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?" "Because dumbass," the navigator answered, "I'll know we're lost before you will."
