Random story...
When I was at Uni (BA hons in Fine Art) I did my dissertation (10000 words!) on 'Is Star Wars the greatest work of art ever?' (most other people were writing about 'use of form and colour in expresionist europe 1890-1910' and other pretentiousness).
During this time I lived in a town in Surrey where several midgets happend to live and I thought I recognised one of them as Kenny 'R2' Baker, I looked in the local phone book and couldnt believe my luck when I discovered a 'K Baker' lived locally.
I worked in a local supermarket on a saturady and knew that within a couple of weeks I'd bump into this individual, I could then interview him for my essay.
A short while later, there he was with his equally small wife and I ran up to him shouting 'are you the bloke that played R2-D2 in Star Wars?'...
He told me to '**** off'...
I didnt even think to ask if he was Mr Baker, and I failed my essay as it was ****.
