Nonsense Limerick....but aren't all limericks nonsense?

I sit here and my mind goes blank
..........................yep, still blank
for what does one say
on a day like today
"Oh, look! There goes a dog who's named Hank!"

I realize that this is ridiculous
for who will read something so frivolous
remember it's spring
that must be the thing
something something something meticulous

I'm waiting for thoughts with a clue
but so far it's gobble-de-goo
what happens a lot
when my mind has not thought
is I hope for a thought residue

A thought residue gives one hope
just like Frances will be a good pope
but really it's clear
that I just want to hear
a rhyme with the word cantaloupe

I promise that this is the end
such nonsense does sometimes offend
that's not my objective
to be ineffective
I'd rather be everyones friend
