Brings to mind the scenes in Mel Brooks’ “Spaceballs” where the Spaceballs get the King of Planet Druidia to tell them the secret combination for the portal to the shield protecting Druidia’s atmosphere – “1 2 3 4 5”. Spaceball’s Darth Vader character, Dark Helmet, says, “That’s the stupidest secret combination I’ve ever heard of! That’s a combination an idiot would have on his luggage!” When they tell the President of planet Spaceball, President Stroob, what it is, he says, “That’s amazing! I have the same combination on my luggage!”
