Pamela Anderson – Bad Celebrity Tattoos

Boobtastic 'Baywatch' star Pamela Anderson has made worse mistakes in the world than this barbed wire arm tattoo -- namely her sex tape with her former hubby, Motley Crue drummer Tommy Lee.

That doesn't give her an out on this list, it just makes her an easier target. As though the sex vid didn't make that a permanent part of her resume already.

Regardless, we don't recommend getting any implement that's used to keep prisoners in and intruders out tattooed on any part of your body. Namely barbed wire, moat-dwelling alligators and laser beams.

Also, tribal. Never, ever tribal. Just say no, kids.
