My favorite line is when Clark's dad looks at the unlit lights all over the house and says, sagely "Well Clark, my advice is to take 'em all down and check 'em one-by-one, because if one goes out, then they all go out. If you need my help, I'll be upstairs, asleep."

Rog is right as well about the squirrel scene - Best. Face. Ever.

This movie leaves all the other vacation movies in the dust, except maybe Vegas, which it still beats by a long way.
