Who is a gentelman that loves to hear himself talk?

Since you catigorized this in Romeo and Juliet I'm going to assume you mean a character in the play. A character in Romeo and Juliet that loves to hear himself talk is Mercutio because he often goes into meaningless and long- winded speeches such as the Queen Mab Speech and when he describes Benvolio as being hot tempered. If you didn't mean to catigorize this in Romeo and Juliet and don't know what the heck I'm talking about in the second paragraph google "sparknotes nfs" (it is the first link that shows up) it' every single one of Shakespheares plays plus a modern day translation. That is...if you're interested.
