This is a Satisfying Phrase
, for some reason.
Some days, you just get fed up with all the crap you have to put up with. You care about porpoises because they're beautiful and intelligent and you ought to, in this enlightened world, so you feed 'em fish and let 'em grow fat and sassy, while you research replacements for spermaceti that work half as well and cost twice as much in your smelly lab.
Sometimes, it feels good to just yell, "Damn porpoises!", take a deep breath, and get on with your life.
Especially if said life involves porpoises.
It's a mental thing, akin to cleaning your toilet.
