Up until about age 12 I was thoroughly convinced that my great grandfather had been on the Titanic. It turns out, he had just used the Titanic as an example to explain that he was on a big ship like that when he was in the Navy. It registered in my brain though and I remember telling all my friends at school that he had been on the Titanic. Needless to say it's impossible seeing as there weren't too many survivors and he was definitley not the right age.
