Deck a hedgehog, and he will seem a lord.
The source for the proverb is English Proverbs and Proverbial Phrases by William Carew Hazlitt (GoogleBooks). And here is Hazlitt's note: “So said of a base Boure that will ranke himselfe out of his ranke.”—W. MS. Rawlinson, c. 86, fol. 31, quoted by Mr. Furnivall (Babees Book, &c., 1868).
