Happy and you know it (tween version)

For some strange reason, I started singing "If You're Happy And You Know It".  Noah had a ball in his hands at the time, and he joined in with his own verse: "If you're happy and you know it, hit your sis!" and proceeded to throw the ball at Sarah.  She flew into a rage and started yelling at him and crying, and I grabbed the ball and continued the song (at a higher volume) with this verse: "If you're happy and you know it....take revenge!" and whipped the ball at Noah.  That could have backfired, but it actually worked.  Sarah stopped the crocodile tears and started laughing, and Noah laughed too, and soon we were all rolling around laughing and making up ridiculous verses to the old classic toddler tune.
