Quote from Sam in I Will Gladly Pay You Tuesday
Diane: Sam, I know you to be a man of pride and principle, but strength is also to be found in the ability to bend. Witness the willow, nature's strongest tree.
Sam: No, I thought the oak was the strongest tree.
Diane: Only in furniture.
Sam: What about the saying "strong as the mighty oak"?
Diane: The oak can be felled by a single harsh wind under the right circumstances.
Sam: All right, but what about birch and mahogany? Now, those--
Diane: Would you shut up about the damn trees?
Sam: You brought them up.
