George is the first to speak, "he's right you know".
Jack grabs a piece of paper from a lab bench and begins writing on it, "right about what?", he asks absentmindedly.
'It would be worth coming back just for the food', George replies with complete sincerity. He turns to look over Jack's shoulder, 'what are you writing?' Jack finishes his scribbling and shows the paper to George, '16431879196842', he reads aloud, 'what the heck does that mean?'
'Paul will need it in about an hour or so, I'll explain on the way back to the Graf Zeppelin', Jack says, lodging the paper partially under a reference book so it doesn't move.
'Couldn't we just stay for lunch?'
Jack laughs as the two walk out the door and head towards the Graf Zeppelin.
