If You're Happy and You Know It

Cade comes home last night singing If You're Happy and You Know It, except for his version is: "If you're happy and you know (long pause) CLAP!" Christian and I tried to sing with him the right way and he said, "That's what I said, Mom!" Then he starts singing again, "If you're happy and you know (long pause) CLAP!" Whatever works. :)
