This one tickled me with its simplicity.
21. Nicolas Cage has a Ghost Rider tattoo on his arm, which he had to cover up when starring in the movie, Ghost Rider. Because even Ghost Rider doesn't have a Ghost Rider tattoo.
It's actually really weird to think of Nicolas Cage having a son.
Funny thing is that I was recently listening to him on the Criterion commentary track for The Rock, and he sounds so NOT weird. Just soft-spoken and articulate. Not that such people aren't weird...
