But in all seriousness, how could anyone think this story is in any way shape of form even remotely possible?

What I've heard about insects and spiders is that they cannot get much larger, if any, than they are do to their respiratory system.
Most insects rely on a passive breathing system where air just flows in and out of a hole, not forced in and out the way we breathe and other animals, or absorb oxygen thru their skin.
This alone restricts their size due to the fact that if they were larger, they couldn't absorb enough oxygen.
Spiders and insects would have to have a respiratory system similiar to ours in order to grow very large.
I heard this a long time ago, I think I've decribed it correctly, please feel free to correct me if I'm wrong.
