歌词：

It isn't any trouble just to S-M-I-L-E.

So smile when you are in trouble.

it will vanish like a bubble.

If you'll only take the trouble just to S-M-I-L-E.

It isn't any trouble just to L-A-U-G-H.

It isn't any trouble just to L-A-U-G-H.

So laugh when you are in trouble.

it will vanish like a bubble.

If you'll only take the trouble just to L-A-U-G-H.
