What does Miley Cyrus have at Christmas? Twerky. This, according to a poll by the comedy channel Gold, is the nation's favourite new festive joke and as such will feature in a specially commissioned box of comedy crackers this Christmas. I think I preferred the runner-up - Why is it getting harder to buy Advent calendars? Because their days are numbered - but they're neither of them close to the all-time classic: How do snowmen get around? They ride an icicle. You can have that one.
