DROMIO OF SYRACUSE: Marry, he must have a long spoon that must eat with the devil.

William Shakespeare (1564-1616) English dramatist and poet

The phrase was popularized by Shakespeare, but had appeared earlier, e.g., Chaucer, "The Squire's Tale," ll. 602-603, Canterbury Tales (c. 1386):

"Therfor bihoveth him a ful long spoon
That shal ete with a feend," thus herde I seye.
