In sixth form my hair started to get towards a decent length and I had photochromic lenses in my glasses, I was/am also tall. I was pretty much universally known as 'Joey' (Ramone).
I went to Uni and didn't tell anyone about my nickname, but for four or five years more people called me Joey than Neil... despite my flowing locks getting far longer. Some people got freaked out when people called me Neil and I responded.
Some years after the hair went short a few people told me I looked like Peter Buck (took me a while to suss out who he was without the net...)
These days George Clooney gets mistaken for me 🙂
