"You see, take
a gun (they are all over the place), put a bullet in there (also easy).
Now locate the whereabouts of Gerry (requires some doingness), then go to
him (take a plane, that's fastest), wait for him (at some place), pull your
gun (does not require much musclepower), then aim (some will have problems
with this), and finally pull the trigger..(keep your hand steady or you'll
miss altogether). Easy no?"
