There was a lad in my year who to this day, still calls me Gilbert (I'm called James really) cos when he first met me in a pe lessonand didn't know my name, I had a rugby bib on. I also got called 'giblet' as well by a few people.
Then my best mate ( comes on here) was known as Bunsen by one of our science teachers cos he's ginger (strawberry blonde i think he calls himself :p)
