The Life and Opinions of Tristram Shandy, Gentleman Book 3, Chapter 36 Summary
The most disappointing book out of the whole bunch was a dialogue about the uses of long noses. Tristram suspects you might be thinking dirty thoughts again—so don't. If Satan gets hold of you, Tristram says, buck him off—with a long list of very, very suggestive verbs.
Read on, he says, or you won't be able to figure out the meaning of the next marbled* page. (And here, Tristram actually inserts a marbled page.)
*Marbling is the swirly coloring you sometimes see on the covers and insides of old books.
