Clark: I've spent the last 15 years of my life developing newer and better food additives. I guess I've missed an awful lot. At first, I didn't want to take this vacation. But, now I'm glad I did. It's given me a chance to spend a lot more time with ...

Clark: [to the campground cashier] 37 dollars for three tents?
Ellen Griswold: Clark, I need my vanity case. We've got to go back and look for it. All my credit cards are in it. Clark: Honey, Number 1: I've already called the bank and told them you lost them. B: there's no way we're going to find it when we don'...
