I have a limerick for you!
I once heard a penguin opine,
There's no nesting finer than mine,
and wouldn't you know,
with the pride it did show,
it found itself facing a line!
For penguins are known to be greedy,
not caring at all for the needy,
so when it did boast,
the fault they all host
roused claimants a-waddle and deedy.
