This is a wonderful discovery! Katie and her friends decided to merge two things I've done on the show recently: Surprise Shakespeare (reinacting a famous scene from The Bard on Public Transport and my reinactment of a famous scene from Titanic with Kate Winslet.

This time, in a supermarket carpark.

Here is Surprise Titanic!

I would like to encourage you all to have a go at this. Maybe at school, college or your place of work. Stop everything and bash out a bit of Titanic. It'll make a boring day much more interesting...

Send it to me: greg.james@bbc.co.uk and I'll put the best ones on the blog.
