Greta: Mr. Reede, several years ago a friend of mine had a burglar on her roof, a burglar. He fell through the kitchen skylight, landed on a cutting board, on a butcher's knife, cutting his leg. The burglar sued my friend, he sued my friend. And because of guys like you *he won*. My friend had to pay the burglar $6,000. Is that justice?
Fletcher: No!
[Greta looks pleased, but then Fletcher continues]
Fletcher: I'd have got him ten.
[Greta stalks off, appalled]
