If You Don't Know What's A True Friend

If you don't know what's a true friend,

Gentle reader, I will tell you,

Though I own, I never saw one :

Well! a true friend's — but you mustn't let

Even your dearest or nearest

Know I ever said or thought it —

Any one who such a fool is

As to give his quid before he's

Quite sure that he'll get a quo for it.
