The sun comes out, the sun goes in,
The raindrops halt and march;
And when you're sure of damp and ark
Up comes the rainbow's arch.

Then, when you're sure of sun and shine,
Down comes the pouring rain!

The weather swings from fair to foul,
From foul to fair again.

There's neither rhyme nor reason here,
There's neither rhyme nor rule.
It's evident the April day
Is playing - April Fool.
