If you're happy and you know it clamp your hand
If you're happy and you know it clamp your hand
If you're happy and you know it
then, your face will surely show it
If you're happy and you know it clamp your hand

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
then, your face will surely show it
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
then, your face will surely show it
If you're happy and you know it shout 'hurray"

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