Animal Crackers
作词 : Ogden Nash；
作曲 : Eric Whitacre
The Panther：
The panther is like a leopard,
Except it hasn't been peppered.
Should you behold a panther crouch,
Prepare to say Ouch.
Better yet, if called by a panther,
Don't anther.

The Cow
The cow is of the bovine ilk
one end is moo
the other,milk

The Firefly
The firefly's flame
Is something for which science has no name.
I can think of nothing eerier.
Than flying around with an unidentified glow 
on a person's posterior
