They don't worry me, which is good, but they are just little freaky things. BUT I'll watch TV shows on them all freaking day. Jellyfish can be found in all the world's oceans, and a few even inhabit freshwater. Over 95% water themselves, they have no heart, blood, brain, or gills. I've worked with folks like this as well. 95% water, no brains, no blood, no guts at all. I leave you with these deep thoughts. Living water creatures. Where's the living dirt creatures?
And then there's the Sims. Caught me again. Loves me that little game.
