A man goes up to the ticket desk at the airport. The ticket clerk says 'Good morning, sir. Can I help you?' and the man says 'Good morning. I'd like a ticket to Tokyo, please'. 'And I'd like you to send my luggage to New York'. Well, the ticket clerk looks surprised and says 'You want us to put you on a plane to Tokyo and send your luggage on a plane to New York?' 'Yes, that's right' says the man. 'I'm very sorry sir but we can't do that – it's impossible'. The man says 'Well, I don't understand why it's so difficult'. 'That's exactly what you did last time'. https://339efcb25eb75e967b0d-ff8eeadd950d51fd1fc939dca75b3973.ssl.cf1.rackcdn.com/assets_green.swf
