The Dinner Party Question

I was once looking up questions on the internet to contribute to a long-winded game of 20 Questions.
I was tired of "what is your favorite color?" and "where do you want to travel?"
I wanted something original. Finally, I stumbled upon the perfect question: 

You are hosting a dinner party. You have ten seats at your dinner table, and you must have the same amount of men and women. You can invite anyone who has ever existed, as long as they were not fictional characters. Who do you invite?

I never asked this question. I was too busy reflecting on who I would invite to my dinner party. 10 is an intimate group; who would I want to spend an evening in close company with? Attractive celebrities? Great philosophers? Tyrannical dictators? The possibilities were endless. After vexing my brain for some time, I came up with a definitive answer.

Here is my hypothetical dinner table.

I decided that if I were to have a dinner party, I would want to gather the wittiest voices I could think of and put them at one table. I would then sit back and enjoy the wisecracks. Yes, I can see it now. "We shall party and repartee and do the same next Tuesday!" If you do not know who any of these people are, I highly recommend looking them up, or at least a few of their quotes. These people inspire me; I have framed Oscar Wilde quotes on my writing desk and Mark Twain has commandeered my bookshelf.

I wish this hypothetical scenario could actually happen. Alas, I fear it never shall. However, Mark Twain gives me hope. He once said, "go to Heaven for the climate and Hell for the company." 

Mark Twain and company, I shall see you all when I get to Hell. Please keep the table set; I am ready for some fiery conversations.
