3 elderly gentlemen were sitting on a park bench discussing what the meanest animal in the world was.

The first said, The meanest animal in the world is a Hippopotamus, cause its got such big jowls. One bite and your gone.

The second shook his head and said Nah, hippo may be mean, but aint nothing meaner than an alligator. He got a big mouth and all them teeth, snap ?, one bite, ha, one swallow, you gone.

The third gentleman sat for a moment, and finally he spoke and said, No sir, the meanest aninmal in the world is a hippagator.

The other two in disbelief inquired as to what in the world is a hippagator, believing there was no such animal.

The gentleman slowly began to explain, A hippagator got a hippo head on one end, and an gator head on the other

WAIT ! interrupted the others, If he has a head on both ends, How does he shit ?

The reply was simply, He dont, thats what makes him so mean.
