Metallica is always a cool theme for anything. Tattoos, black t-shirts, bumper stickers, birthday cakes, whatever. My personal favorite metallic logo was the "metal up your ass" shirt of the late 80's. When I was in high school wearing that shirt meant instant detention.
When I am not carving pumpkins, I run the world's most private drugstore. ShopInPrivate.com
Also, last year, my company took over RomanticGifts.com, so if you need a romantic gift for Christmas, a birthday or an anniversary, please consider our wonderful store.
My co-workers and I run the biggest store for bachelorette party items in the world. It is lots of fun. We have fun jobs.
