Who would you like to sit next to if you were on a long flight and wanted to indulge in conversation with a stranger?

Of course my 1st choice would be Spotwelder.(Although He is not a stranger, but a little bit strange!) However if he isn't available due to his rigorous schedule then I would have to chose Robert Carlyle, Michael Palin or Kevin Spacey.

So who would you like to sit next to and why?
