Platypus

Elvis the platypus was eating his duckweed one night at his kitchen table when he heard a strange noise outside his hut. He got up, duckweed in hand and went to the window; outside, hanging from a tree was a strange primate that he had never seen before. The creature was three feet tall and had a black goatee, Elvis handed out his duckweed to the strange creature, who swung over and grabbed it out Elvis' flipper. Elvis was startled by this, but when he saw the sweet look in the creature's eye he smiled. The creature nibbled at the duckweed, squinted its eyes, spit out the chewed plant and showed rows and rows of sharp fangs. The zebra police found nothing but a platypus' tail and blood stains the next morning.

Moral: never trust strangers
