- c. 27 CE – 66 CE, Petronius, Satyricon 61:
  Niceros delectatus affabilitate amici: "Omne me, inquit, lucrum transeat, nisi iam dudum gaudimonio dissilio, quod te talem video. Itaque hilaria mera sint, etsi timeo istos scolasticos ne me rideant. Viderint: narrabo tamen, quid enim mihi aufert, qui ridet? Satius est rideri quam derideri."
  Niceros was delighted by his friend's amiability and said, “May I never turn another penny if I am not ready to burst with joy at seeing you in such a good humour. Well, it shall be pure fun then, though I am afraid your clever friends will laugh at me. Still, let them; I will tell my story; what harm does a man's laugh do me? Being laughed at is more satisfactory than being sneered at.”
