Tim Vine has been travelling the length and breadth of this fair land to uncover the best stories of the Great British public.

But he also takes every possible opportunity to tell a ridiculous joke and sing a preposterous song along the way.

Tim arrives in London and parks his Chat Show wagon in Greenwich, where he chats to a museum curator about airport security.

Plus there's a song about cake and milk.
