An Amazon user's review of the BIC ballpoint pen
"Today is the fourth day of ownership of my pen, and I have to say I'm starting to treat it like an old friend. ..In summary, I would happily recommend this pen to anyone who is planning on writing on paper."
This review about a duck called Ping "describes networking in terms even a child could understand, choosing to anthropomorphize the underlying packet structure. The ping packet is described as a duck, who, with other packets (more ducks), spends a certain period of time on the host machine (the wise-eyed boat). At the same time each day (I suspect this is scheduled under cron), the little packets (ducks) exit the host (boat) by way of a bridge (a bridge). From the bridge, the packets travel onto the internet (here embodied by the Yangtze River)."
