It has come to my attention that 3 year old ds believes all the many Justin's on Something Special are different people 
We are currently watching it and Lord Tumble appears. I say 'its Justin'. Ds looks absolutely outraged and proceeds to tell me that it's Lord Tumble. Pans back to Justin to be told 'there Justin mummy'.
He has now named all of them including Aunt Polly and Grandad Tumble. He has not a clue that they are in fact the same person.
Did/does your dc recognise Mr Tumble as Justin or do they see them as different people? I'm quite frankly amazed, I didn't think he was fooling anyone!
