Puzzles (Children) Poem by Herbert Nehrlich

Good news, my friends it has been found
that, pear-shaped though, the earth is round.
That water drains from in the sink
left-turning, same as when you drink.
The stripes on zebras, are they white?
On skin that's black, could that be right?
Or are they black on bleached white skin
and why might horses, next of kin,
have neither stripes nor spots nor fur,
do leopards (really felines) purr?
Just questions, can you solve the riddle
why kiwis have a dark green middle?
And why tomatoes wear red suits?
It is because they may be fruits.
I'll leave you now, perhaps you're clever
and find the answers (never, never!) .
