You know the game, you can invite ten real people - alive or dead - who you would want to have around the table for a meal and conversation. Since it's a fantasy, language wouldn't be a barrier.
I'm still working on my definitive list but some names come immediately to mind;
Stephen Fry
Adrianna Lima
Carl Sagan
Lee Evans
Peter Kay
Elvis
Jessica Rabbit
Jeanne d'Arc
Nimrod
Jessica Rabbit
And perhaps the Beatles are playing in the corner.
Hmm I need to think on this . . . .
