Zebra
Looks like a horse, but it has black-and-white stripes, which help it camouflage
itself in the green-and-brown veldts of central Africa. Living proof that evolution
sometimes really cocks it up.
Zenda
No idea where it is, but there's a prison there, presumably.
Zoo
Zoos were invented in the days before David Attenborough, and this accounts for both their political and emotional unacceptability, and the fact that they're generally tawdry and horrible. The fact is that, if you want to see hippos copulating or three-toed sloths demonstrating how they lick between their toes, you can buy a video of Life on Earth. What there is no point in doing is going and peering through some rusty wire fence at a hut and a pile of straw while your parents say, 'It's inside at the moment, It'll come out in the minute.'
The impact of TV on zoos has meant that most zoos have had to turn themselves into a theme park with some animals in it. Chessington Zoo is now called Chessington World of Adventures largely because kids in the 1990s were more interested in travelling on a monorail than watching a giraffe having a shit. All you ever saw as you went round the zoo, was dilating anuses and globs of smelly brown matter hitting the concrete. This also meant that zoos smelt of poo. And this is another reason why it's better to see animals on telly - because you don't have to smell their poo.
Of course, one interesting thing that could happen at the zoo would be that you might see a male animal with an erection, and this was good for embarrassing your parents with. It was always a good laugh to have to watch the elephant wandering around with an enormous stiffy, while mum and dad hurriedly decided it was time for ice cream.
