Thanks for the welcome! I didn't want to just barge in, but I had so much fun with this last night, I confess, I was itching to share it.

OK. I combined the Petrarchan and Shakespearean forms (it was late!) with an octave of ababcdcd and a sestet of efgefg.

Raining Cats and Frogs

When angels weep and startled toads descend
from out the cloud-veiled heavens in a burst
of rain, my common sense leaps to defend
my brain from overload. Unless were cursed
with Egypts ancient plagues I cant see how
amphibians can shower from above.
And why not larger beasts (perhaps a cow)
the cherubs out of heaven thus might shove?
Still, since these frogs are croaking round my feet
the best of it I set myself to make
by putting to good use what hast been given.
Trefuse angelic bounty is not meet,
so I will set aside my taste for steak
and glut on frog-legs lightning-fried in heaven.

If this offends anyone's poetic sensibilities, I apologise. Sometimes traditional form just seems to be crying out for ridiculosity to be applied.
