Herbert Nehrlich - Limericks Today**

A Leopard is really a cat,
and a cat is not usually fat
even elephant shots
will not alter his spots.
Though no spots can be found on his hat.

An old donkey is really an ass,
he will NOT make a pass on a lass,
quite content to abstain
he will use his small brain
to just stand there and eat the green grass.
