Hippopotamus-another by Jim Cornish

The hippopotamus is a big
and most ungainly kind of pig.
He doesn't know he is of course,
he thinks he is a sort of horse
and that's because some ancient Greek
who, seeing this animal in a creek,
said "It isn't reptile, cat or kine
ergo it must be equine."
He doesn't gallop, trot or neigh
and doesn't lunch on oats and hay.
He's lacking the essential parts
convenient for pulling carts.
He doesn't grunt or squeal or snort;
(perhaps he thinks he shouldn't ought)
so leave him wallowing in his bog
pretending that he's not a hog.
