"Rain, Rain, Go Away" is a short children's rhyme:

Rain, rain, go away.

Come again some other day.

There are several longer versions, the most common of which is:

Rain, rain, go away,

Come again another day.

Rain, rain, go away.

Come again some other day.

Little Johnny wants to play,

In the meadow by the hay.

Rain, rain, go to Spain,

Never show your face again.

Rain, rain, pour down,

But not a drop on our town.

Rain on the green grass,

and rain on the tree,

And rain on the housetop,

but not on me.

Rain, rain, go away,

Come again on washing day.

Rain, rain, go to Germany,

And remain there permanently.

Rain, rain, go away,

Come on Martha's wedding day.

Additional Verses:

Rain, rain, go away,

Come again another day,

If you don't, I will say,

Rain, rain go away.

Rain, rain, go away,

Come again some other day,

We want to go outside and play,

Come again some other day.

Rain, rain, go away,

Come again some other day,

If you don't, I don't care,

I'll pull down your underwear!

As with many nursery rhymes the origin and meaning of this one is open for debate, but one theory is it dates to the time of Spanish Armada, and its failure due, in part, to bad weather. It also shares its lines with another popular nursery rhyme, "It's Raining, It's Pouring".

It's raining, it's pouring,

The old man is snoring,

He went to bed and bumped his head

And couldn't get up in the morning.
