That's a Good One! (As Something Ha-ha Funny)

"Did not we agree to take a drive this morning? What a head you have! We are going to Claverton Down."

"Something was said about it, I remember," said Catherine, looking at Mrs. Allen for her opinion; "but really I did not expect you."

"Not expect me! That's a good one! And what dust you would have made, if I had not come."

--Jane Austen, Northanger Abbey, Chapter 9
