This is hilarious. But, I suppose, necessary.
Dr. Justin O Schmidt, an entomologist (scientist who studies insects) who until recently worked for the U.S. Department of Agriculture, produced a 4 point scale to rate the pain inflicted by insect stings.
Short version (in case you don’t want to follow the link): don’t get stung by an Amazonian Bullet Ant. Ever.
He describes that as “Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail in your heel.”
Phew!
