Calvin: If I've learned one thing in life, it's that everyone has his price.
Calvin: Raise the ante high enougn, and there's no such thing as scruples! People will do anything if the price is right!
Hobbes: What's your price?
Calvin: Two bucks cold cash up front.
Hobbes: I don't know which is worse, that everyone has his price, or that the price is always so low.
Calvin: I'd make mine higher, but it's hard to find buyers as it is.
