Emma

Jane Austen, Emma:

"I like your plan," cried Mr. Weston. "Agreed, agreed. I will do my best. I am making a conundrum. How will a conundrum reckon?"
"Low, I am afraid, sir, very low," answered his son;—"but we shall be indulgent—especially to any one who leads the way."
"No, no," said Emma, "it will not reckon low. A conundrum of Mr. Weston's shall clear him and his next neighbour. Come, sir, pray let me hear it."
"I doubt its being very clever myself," said Mr. Weston. "It is too much a matter of fact, but here it is.—What two letters of the alphabet are there, that express perfection?"
"What two letters!—express perfection! I am sure I do not know."
"Ah! you will never guess. You, (to Emma), I am certain, will never guess.—I will tell you.—M. and A.—Em-ma.—Do you understand?"
Understanding and gratification came together. It might be a very indifferent piece of wit, but Emma found a great deal to laugh at and enjoy in it—and so did Frank and Harriet.—It did not seem to touch the rest of the party equally; some looked very stupid about it, and Mr. Knightley gravely said,
"This explains the sort of clever thing that is wanted, and Mr. Weston has done very well for himself; but he must have knocked up every body else. Perfection should not have come quite so soon."
