If you're happy and you know it shout out
If you're happy and you know it
And you really want to show it
If you're happy and you know it shout out

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 laugh out
If you're happy and you know it
