If shakespeare doesn't suit, how about Sheridan's "The Rivals":

Abs. Spoke like a man! But pray, Bob, I observe you have got an odd kind of a new method of swearing—

Acres. Ha! ha! you’ve taken notice of it—’tis genteel, isn’t it!—I didn’t invent it myself though; but a commander
in our militia, a great scholar, I assure you, says that there is no meaning in the common oaths, and
that nothing but their antiquity makes them respectable; because, he says, the ancients would never
stick to an oath or two, but would say, by Jove! or by Bacchus! or by Mars! or by Venus! or by Pallas,
according to the sentiment: so that to swear with propriety, says my little major, the oath should be an
echo to the sense; and this we call the oath referential, or sentimental swearing—ha! ha! ’tis genteel,
isn’t it.

Abs. Very genteel, and very new, indeed!—and I dare say will supplant all other figures of imprecation.

Acres. Ay, ay, the best terms will grow obsolete.—Damns have had their day.
