Ya ha ho and a chuckle and a giggle, And a great big laugh that comes from the middle, Nobody knows what it's all about But when it happens it knocks you out. Chorus: Ya ha ho, Ya ha ho, Once it gets started it has to go. I laugh, so do you, And soon everybody's laughing, laughing, Everybody's laughing too. A laugh is something that you can't buy, You can't make it happen if you try, But some little thing or some little word And everybody's laughing like a coo-coo bird. (Chorus)
