This song was recorded last century by Alfred B. Smith, and clapped, stomped and hurray-ed to by millions of kids ever since.

If you're happy and you know it, clap your hands
If you're happy and you know it, clap your hands
If you're happy and you know it, and you really want to show it
If you're happy and you know it, clap your hands.

If you're happy and you know it, stomp your feet
If you're happy and you know it, stomp your feet
If you're happy and you know it, and you really want to show it t
If you're happy and you know it, stomp your feet.

If you're happy and you know it, shout "Hurray!"
If you're happy and you know it, shout "Hurray!"
If you're happy and you know it, and you really want to show it
If you're happy and you know it, shout "Hurray!"
