Is it true that William Shakespeare...?

Absolutely he recognized that we are ual beings. I disagree with the "low-brow" comment. The English at that time were not as prudish as we are in America today. Parents today would be appalled at the ual references being pointed out in R&J. In my opinion, the dirtiest joke in all of Shakespeare is in this play. Read Mercutio closely when Romeo appears in the square the morning after the balcony scene and ask yourself what "fishified" could possibly mean. Or what does the Nurse mean when she says, Thou wilt have more wit when thou fallest backwards. Ok, that's paraphrased, but contains the general idea. Oh, oh and my favorite from Othello, "they make the beast with two backs"... priceless. Did Shakespeare appeal to the groundlings? Of course he did, he also did not talk-down to them. He elevated the language, which they spoke but could not read, and they loved him for it. Don't be offended, revel in the forthright and honest reference to what each of us is.
