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 hell!" roars the lion. "Not finch and chimps again!"
