I have two kids - 5 and 2 - and I'm hearing all those songs I heard as a kid. Only they've morphed over the years.

Jingle Bells, Batman smells, Robin layed an egg... I had completely forgotten that one until last Christmas.

But for the life of me, I can't figure: How did "Happy Birthday" pick up a "Cha Cha Cha" between most lines? That one really annoys me.
