You should see the cockroaches in South Africa. Good God.
Step on them, and you just piss them off.
Spray insect killer on them, and they jump up and attack the spray can.
Kick them, and they just jump up and attack YOU.
They SCREAM when you try to kill them, I kid you not, and they spray a foul substance out of their asses.
They have horrible claws all over their legs, big thorny ones.
Even dogs are afraid of these things.
