Bob Z really got the party started. And look at him with his sunglasses all lookin' like a rock star.

Here's another angle of Bob.

Hosts Hooter and Greenway were hurting after Hoot's bachelor party the night before (especially Hooter). A2J chills in the background and the Hale's just relax and enjoy that which was House Party 4.

The Hales enjoy the show ... although Jason refuses to smile.
