SMILE 

It isn't any trouble just to S-M-I-L-E, 
It isn't any trouble just to S-M-I-L-E, 
So smile when you're in trouble 
It will vanish like a bubble, 
If you onfy 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 to be H-A-P-P-Y.... 
It isn't any trouble just to S-M-I-L-E....
