Ok, maybe not my first one, but one of them any way.
"You are allowed to name your character after a Lords of the Rings character. But only once."
I think we have all done it and then later in life thought "man what was I thinking?". I had a halfing thief named Bilbo. My son is in the "regret" stage now with his wizard named "Gandalf". I told him not to worry that everyone has done it (que a bunch of replies of people saying "I never did!").
So instead of feeling bad about it I say embrace it. Own it.
Galdalf was named after a legendary near-mythical wizard. With a name like that he was bound for greatness. Bilbo is a very popular name among halflings, as is Frodo and Sam.
So here is where I have to ask. Did anyone name a character after a Tolkien character?
