Dorothy Parker, while playing a word game, was once asked to use the word "horticulture" in a sentence. She instantly replied, "You can lead a whore to culture, but you can't make her think". This was a parody of the old saw, "You can lead a horse to water but you can't make it drink", of course.
If you enjoy the Parker wit, you can find a bucketload of it here:
