Something Else To Eat

A cannibal father and son went hunting. Deep in the jungle, they hid beside a trail. Soon, a little old man walked by. The son whispered, "Dad! There's one. Let's get him!"
"No," said his father. "Not enough meat. We wait."
Later, a fat man came along. "Dad! He's huge. Let's get him!"
"No," his father said. "We'd all have heart attacks from all the fat in him. We wait."
Hour later, an absolutely gorgeous woman approached.
"Dad! There's nothing wrong with that one. Let's eat her."
"No," said his father. "We'll not eat her either."
"Why not?"
"We'll take her home alive and eat your mother!"
