Earlier today I got to use the word "pandering" in IM conversation, just hoping that I'd get to point out that the word comes from Pandarus, a Shakespearean character. Alas, no such luck.
However, not 5 minutes ago I heard a hallway conversation from two cubes over on the derivation of the character "Lothario." Before the inevitable "I wonder if it's a Shakespeare thing. Hey Duane?" came lofting my way I'd already googled enough to answer, "Nope, not Shakespeare, he's apparently from a 1703 play by Nicholas Rowe called The Fair Penitent." I like anticipating when I'm needed. :)
Although interesting, the Wikipedia is unclear on whether Rowe's character is in fact the origin. There's a reference to a Lothario in Don Quixote, which was 100 years previous. So perhaps Cervantes is the originator of the name? In that case Shakespeare could also have known of the character. Maybe he shows up in Cardenio!
