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)
