... don't get caught like the turtle and the little girl.
The Scorpion and the Turtle
A scorpion, being a very poor swimmer, asked a turtle to carry him on his back across a river. "Are you mad?" exclaimed the turtle. "You'll sting me while I'm swimming and I'll drown."
"My dear turtle," laughed the scorpion, "if I were to sting you, you would drown and I would go down with you. Now where is the logic in that?"
"You're right!" cried the turtle. "Hop on!" The scorpion climbed aboard and halfway across the river gave the turtle a mighty sting. As they both sank to the bottom, the turtle resignedly said:
"Do you mind if I ask you something? You said there'd be no logic in your stinging me. Why did you do it?"
"It has nothing to do with logic," the drowning scorpion sadly replied. "It's just my character."
The Girl and The Snake
This girl finds a snake that pleads with her to place it in her winter coat because otherwise the snake will freeze.
The girl goes "No you'll bite me blah blah blah".
Anyway the girl eventually puts the snake in her jacket to keep it warm and she continues on her walk.
Then she feels a sharp pain in her side, the snake drops out and begins to slither away.
The girl say something like "Why? I took care of you, blah blah blah".
The snake simply replies "You knew what I was when you found me".

“Watch out for false prophets. They come to you in sheep's clothing, but inwardly they are ferocious wolves. By their fruit you will recognize them. Do people pick grapes from thornbushes, or figs from thistles?
