There are several sites dedicated to Shakespearean insults. One of my favorites is www.william-shakespeare.org.uk. There's also www.petelevin.com/shakespeare.html These are "insult generators," which include a lists of two adjectives and one noun.

I should also mention KING LEAR: "Thou son and heir of a mongrel b*tch."
In the words of Fr. Donald Lynch: "Isn't Shakespeare great? He can call somone a son of a a b*tch and make it sound like poetry."

Shakespeare, the greatest writer in the English writer who ever lived, wrote some corking great insults. Here's some great ones!

Degenerate and base thou art! - The Two Gentleman of Verona

Me'thinkst thou art a general offence and every man should beat thee - All's Well That Ends Well

We leak in your chimney - Henry IV - Part 1

Thou infectious ill-breeding dewberry

Thou churlish shard-borne codpiece

Thou frothy shard-borne blind-worm!

Thou vain ill-natured bladder

I find the ass in compound with the major part of your syllables - Coriolanus

Thou Villainous scurvy-valiant bum-bailey

Thou hath not so much brain as ear-wax

Wherein [art thou] good, but to taste sack and drink it? Wherein neat and cleanly, but to carve a capon and eat it? Wherein cunning, but in craft? Wherein crafty but in villainy? Wherein villainous, but in all things? Wherein worthy but in nothing?

- Henry VI - Part 1
