Here's the thought that spurred the post: It's Shakespeare Day (April 23, duh) and though you're surrounded by people that know you to be a Shakespeare geek, it's not a typical Shakespeare environment. Your day job, perhaps. A coworker approaches you and says, "So, quote something." You stand on your desk in a Dead Poet's Society moment and quote .... what?
And, why that one? In a situation like that I think of Brando in Julius Caesar, doing the "Friends, Romans, Countrymen!" bit to get their attention. But other than the opener, is that the speech you'd want to demonstrate once you had everybody's attention?
If you're a pro at this, do you choose something that your audience will likely know, or something they've probably never heard?
