Without (the reality), it's just slamming into things. If you start with that physical comedy, then things surely but slowly fall apart. But you build on that reality and then you can go pretty outrageous - up to the Keaton-like gags.

See, the problem is that God gives men a brain and a penis, and only enough blood to run one at a time.

The only weapon we have is comedy.

Reality is just a crutch for people who can't cope with drugs.

The moments of comedy are there. But the whole idea of a vacation is the stripping away of stuff and then, by the end of the vacation, (at least) in my life, you do have these moments as a group, as a family having a great time, so mellow again. It takes a while to do that but that's what this movie is about.

Reality: What a concept!
