Happy April Fools' Day: Here's one of the greatest military pranks we've ever seen

In 1986 a US Navy helicopter crew devised a prank that would go down as one of the best in history.

As the USS John F. Kennedy came to relieve the USS America after a six-month deployment in the Mediterranean, aircrewman Brian Christoff filmed three greased pigs each painted red, white, and blue on the flight deck of the USS Kennedy.

"We used the excuse that we had some official paperwork to drop off. They never seen it coming!" Christoff wrote in the video's description.
