A tourists guide was talking with a group of school kids at Yellowstone park when one of the kids asked him if he had ever came face-to-face with a wolf.
"Yes, I came face to face with a wolf once. And as luck would have it, I was alone and without a weapon."
"What did you do?" the little girl asked.
"What could I do? First, I tried looking him straight in the eyes but he slowly came toward me. I moved back, but he kept coming nearer and nearer. I had to think fast."
"How did you get away?"
"As a last resort, I just turned around and walked quickly to the next cage."
