Graeme Willy: You are an alien!
Paul: To you I am, yes.
Graeme Willy: Are you gonna probe us?
Paul: *Why* does everyone always assume that? What am I doing? Am I harvesting farts? How much can I learn from an ass?

Trivia: The dog at the beginning of the film looks up. This is in reference to Pegg and Frost's characters arguing about whether dogs can look up or not in their film Shaun Of The Dead.
