Drop a pebble in the water - just a splash, and it's gone. but there's half-a-hundred ripples circling on and on and on Spreading, spreading from the center, flowing on out to the sea And there is no way of telling where the end is going to be. Drop a pebble in the water - in a minute you forget. but there's little waves a-flowing, and they're circling yet And those little waves a-flowing to a great big wave have grown you've disturbed a mighty river just by dropping in a stone.

Drop an unkind or careless word - in a minute it is gone. but there's half-a-hundred ripples circling on and on and on They keep spreading, spreading, spreading from the center as they go and there is no way to stop them, once you've started them to flow.

Drop an unkind or careless word - in a minute you forget. but there's little waves a-flowing, and there's ripples circling yet And perhaps in some sad heart a mighty wave of tears you've stirred and disturbed a life that was happy where dropped that unkind word.

Drop a word of cheer and kindness - just a flash and it is gone. but there's half-a hundred ripples circling on and on and on bearing hope and joy and comfort on each splashing, dashing wave till you wouldn't believe the volume of the one kind word you gave.

Drop a word of cheer and kindness - in a minute you forget. but there's gladness still-a-swelling, and there's joy circling yet and you've rolled a wave of comfort whose sweet music can be heard over miles and miles of water just by dropping one kind word.
