Rather than have them together at one meal, I'd prefer to invite one at a time, so I could learn more from each individual.
Politician: I think Ben Franklin would be a great guest...I know the ladies of the French court certainly enjoyed his company.
Actor: Al Pucino would be my next guest...I just love to listen to him talk.
Comedian: Robin Williams would be lots of fun...
Singer: I'd love to fix cheeseburgers for Jimmy Buffet.
Scientist: Carl Sagin...I always found him fascinating.
Chef: Julia Child, of course. We could drink a little wine and cook together.
