When you're smiling, keep on smiling, The whole wide world will smile with you; And when you're laughing (ha, ha, ha, ha!), keep on laughing (ha, ha), You'll find the sun will come shining through! But when you're crying (boo-hoo), you bring on the rain; Stop your sighing and be happy again. When you're smiling, keep on smiling, The whole wide world will smile with you!
