A man goes to Africa on a safari.

While there, he comes upon an elephant, in great pain, with a giant thorn in its foot. The man very carefully approaches the elephant, and gingerly removes the thorn from its foot. The elephant begins to walk away, then turns and stares at the man for a full minute, locking eyes with him. The elephant then continues on its way. "I wonder if I ever see that elephant again if it will remember me?" the man muses to himself.

It is a few years later

The man is at a circus back in the States. He notices that one of the elephants keeps looking at him, almost like it KNOWS him.

The man wonders, "Could this be that elephant I helped so long ago?" He decides to get a closer look. With the elephant still giving him the staredown, the man moves in closer, getting right up in front of the elephant. They lock eyes. A knowing look seems to cross the elephant's face It reaches down ...

...picks the man up carefully with its trunk...

...lifts him high in the air...

...THROWS HIM CRASHING TO THE GROUND AND STOMPS HIM FLAT!

Turns out it wasn't THAT elephant.
