I have heard this one.." that snake will size you up to see if you are a meal!"
They don't understand that even the largest anaconda on the planet would have a difficult time eating a 200 pound adult man... but a 6 pound ball python! If he tried to eat me, I would laugh and eat him! Heck, he couldn't even kill a cat! A cat is much more dangerous animal, they kill far more animals, far more frequently, yet people own tons of these malevolent felines and think they are cute.
