The name Benjamin Button is odd, but the name that always bothered me a little was Brad Pitt. I would ask myself, why choose a name like Pitt for your screen name? This was before I realized that these days, lots of actors keep their own names, regardless, and that Thomas Bradley Pitt was one of them.
It never bothered me that the two Pitts were Prime Minister. Eartha Kitt was OK. Mitt was OK, though I didn't like his politics. I've got nothing against armpits, or fruit pits, or Pittsburgh.
Just seemed like a strange name to choose. Now if he ever marries Angelina (whose real name is Angelina Jolie Voight), she can be Angelina Pitt.
