Here at The Bard and the Bible blog we hope your Monday is going well. As well as can be expected, at least. If not, you may find a trenchant insult from Shakespeare to be useful.
Always hoping to be helpful, we offer this insult from Troilus and Cressida, spoken by Thersites to Ajax:
Thou sodden-witted lord! (Troilus and Cressida, II.1.41).
You’re welcome. Use it wisely.
