Russian Prime Minister Medvedev comes to President Putin and nervously tells him to abolish time zones. " I fly to another city, call home and everyone is asleep. I woke you up at 4AM but I thought it was only evening. - I call Angela Merkel to congratulate her on her birthday and she tells me she had it yesterday. - I wish the Chinese President a happy New Year, and he says it will be tomorrow." "Indeed" Putin replies "but that's only minor stuff, remember when that Polish plane crashed with their president? I called them to express my condolences, but the plane hadn't taken off yet!!"
