Twice five trampoliners:
their nine siblings they'd outshine.
The first lands in his neighbor's yard.
There now remain just nine.
Observe nine trampoliners
try to outperform each mate.
The second soarer sprains his wrist,
which leaves behind but eight.
Voila! Eight trampoliners.
Two exhaust their bags of tricks
while banging all four knees together.
Now are seen just six.
So: six svelt trampoliners.
Shouts the smallest, "Watch me dive!"
Which tree'd he land in...? No one sees.
(At this point, there be five.)
Full five fit trampoliners.
Sev'ral watch their brothers soar.
The last to soar's not seen again.
How many left...? But four.
Four facile trampoliners.
Yells the eldest lad, "Whoo-pee!"
and promptly knocks himself unconscious.
Left to leap...? But three.
Three trusty trampoliners.
Did you see which pull'd a gun
and blithely blew the other two
away -- thus leaving one...?
That solo trampoliner leaps,
as huge -- and hungry! -- birds
swoop down and bite his head off.
Now how many leap...? Two thirds.
