JOKES

On some air bases, the military uses one side of the field and civilian aircraft use the other, with the control tower in between. One day a plane calls the control tower and asks, "What time is it?" The control tower radios back, "Who's calling?" "What's the difference?" the plane's pilot asks.

"There's a lot of difference," replies the control tower. "If you're a commercial flight, it's three o'clock. If you're Air Force, it's 1500 hours. If you're Navy, it's six bells. If you're Army, the big hand is on the twelve and the little hand is on the three."
