When you see spiders or scorpions (especially scorpions), you can't help but believe they'd be a force to be reckoned with if they marched in a phalanx. Alternatively, dinosaurs! According to some, the Jurassic will rise again. So, what's next?
Because spiders and scorpions can't organize, I admit this is just speculation. Dinosaurs with small arms on the other hand may cause some havoc. However, their operating systems do not support holding onto two ideas at one time.
So remember this the next time your day gets a little too hectic: when life hands you lemons, make lemonade. When life throws you militarized velociraptors, just run. Deal with them after lunch.
