     Question:What is more astonishing than a 60-ton whale on a

flatbed truck being driven down the street?

     Answer:A 60-ton whale on a flatbed truck exploding and rai-

ning blubber( fat of whales) all over the sidewalk.

    That's what happened in Taiwan recently,when a dead sperm

whale being shipped to the Halobios Research Centre for an autopsy

(尸体解剖) developed an extremely bad case of gas and blew up

before it reached its destination.

     The whale was found alive on a Taiwan beach last weekend,

and died shortly after it was discovered. Since the 56-foot whale was

the largest whale ever beached on Taiwan's shores,scientists wanted

to study it and perform an autopsy for educational purpose.

      Obviously,too much time passed between when the animal died

and the time it was set to be moved to the autopsy location,because

it had already started to go bad. When things rot,they give off gases

as a by-product. In the whale's case,the gases were trapped in its

belly. The pressure inside the rotting creature grew so much that it

popped like an over-filled balloon. Unfortunately,it was on a truck in

the middle of the city of Taiwan at the time ;cars and shops lining the

street were covered with whale bits and juices,much to their owners'

discouragement.

      According to news reports,traffic was tied up for hours while of

ficials tried to clean up the streets.

     Newspaper editors worldwide were probably smiling to them-

selves,since they had a ready-made headline; several reports about

the incident were titled " There  She  Blows ! " after the famous line

from the book Moby Dick.
