Anyone else think that it is about the stupiest thing in the world?

I pass one up everyday to the parking garage. All I ever see if a bunch of smiling moms in socks, and crying, non careing babies and there seems to be some sort of coach.

Now mind you I have never been in one, just my observations from the windows.

What does the coach do? Tell you to hold your baby and move it to the music?

How does this place make money? I mean why am I going to pay for someone to play music and I dance around with my kid. I can do this at home or at a friends party for free. Then maybe some fuzzy nipples will be involved.
