Destroying the moon using H-bombs

How many H-bombs, equally spaced within the moon and detonate simultaneously, are needed to completely destroy it?

1)calculate the amount of energy it would take to accelerate all of the mass of the moon to it's escape velocity.  remember to take into account things like the escape velocity varying at different layers of the moon
2)look up the amount of energy in an atom bomb
3)simple multiplication

I'm not actually going to do this because it requires more effort than I'm willing to put in right now.  if someone else wants to do it, post the results.  I suspect the result will be pretty ridiculous, but not inconceivable.
