The premise of this scene is Uncle Phil enjoying a moment of perfect relaxation with his children. That face as he exhales says it all. Of course, it's just a set-up for Will to come crashing in and announce that he's dropping out to become a comedian... shattering Uncle Phil's rare blissful moment.
It's pretty cool to watch him yell at Will using the pipe stem as an angry pointer!
I miss the days when it wasn't taboo to show a dad having a moment of supreme relaxation, pipe in hand, surrounded by family.
These days they don't have a problem portraying a dad handling stress by learning to cook meth and going on a crime spree, as long as there's no tobacco involved.
