Three old men Bert, Arnie and Harry were sitting on a park bench debating what the meanest animal in the world was.
Bert said: “The meanest animal in the world is the hippopotamus, because it’s got such huge jaws. One bite and you’re gone!”
Arnie shook his head and said: “No, the hippopotamus may be mean but he’s a p**sycat compared to an alligator. An alligator’s got attitude, and one bite from those teeth, followed by the death roll, and you’re gone!”
Harry thought for a moment before saying: “As a matter of fact, you’re both wrong. The meanest animal in the world is a hippo-gator.”
Bert and Arnie laughed. “What the hell’s a hippo-gator?” they asked “There’s no such creature.”
“A hippo-gator”, explained Harry, “has got a hippo head on one end and an alligator head on the other.”
“Wait a minute!” interrupted Bert and Arnie. “If he has a head on both ends, how does he shit?”
“He doesn’t,” said Harry. “That’s what makes him so mean.”
