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
then your face will surely 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, shout Hooray....
If you're happy and you know it, do all three....
