Bilbo is an old nickname from work, 1967 is a significant year for me.
I was nicknamed Bilbo at work not because of my diminuitive stature, or because I have hairy feet, but because, as new trainees we were allocated to a mentor. My mentor was an older guy who was nicknamed Gandalf (no idea why, he didn't have a beard or long hair or wear a white robe). Anyway, as Gandalf's mentee, Bilbo was the obvious nickname.
Could have been worse, one guy was known as, and forever will be by some of us, as Dickwipe
