Do you ever google yourself? I did today. I found out that a woman with the same name as me is somehow a character on one of these "Real Housewives of..." shows. Same name! She clearly isn't that famous yet, since I only heard of her this way. But imagine someone who had your name became super famous. Like your name is something very normal like "Michael Jackson" and then Michael Jackson comes along....Weird. That would be weird.
Not as weird as being named Theremin though.
An aquaintance named their baby Theremin recently. Their male baby. Yes, like the horror movie instrument. I suppose that reduces the likelyhood that your kid will have their name become famous unintentionally.
