("Robert Bonomi" wrote)
Being a determined man, he decided "this means war". He then purchased a
12th-century catapult which he set up in his back yard.

He then proceeded to launch _cherry_pies_ at the aircraft passing
overhead.

After he scored his third *direct*hit* within a period of a few weeks, the
Air Force sued for peace.
