Cleaning out the aviary at a run-down zoo, the keeper finds two finches
that have died of old age. He picks them up and places them in a sack.
After cleaning the cage he puts the sack in his wheelbarrow and moves on
to the next cage.

When he reaches the primate cage he finds two chimps who have also died
of natural causes. "Waste not, want not," he says as puts them in the
sack with the finches.

Later at feeding time, he flips the dead animals from the sack, into the
lions' cage.

"Bloody bore!" roars the lion. "Not finch and chimps again!"
