Hi Dsherwood,
I may be wrong, but I think the joke pre-dates the film.
On another topic, I notice that you, like me, are amongst the few who have used their names as the id for HotCopper. I'm feeling left out a bit as some of the names used here are pretty cool. I'm thinking I will probably rack my brain for a nice moniker and create a new account soon.
Regards,
Keith
