I'm thinking of a word that starts with a B

Any guesses? I would be very surprised if you guessed correctly: Bobby pencil.

I've wanted to get a picture of Seth with his Bobby-Pencil for some time now. I'm not too worried about it, but it gives me a smile each time he finds one of my bobbypins, he wants me to put it in his hair.... which of course only lasts about 3 mins, but he gets so excited, I doubt it can do any harm. If he was 12 years older... then we might have to talk with him. :) Until then I just have to remember what a bobby pencil is.
