Tattoo

From Conservapedia

Tattooing is a process in which a needle impregnated with ink is repeatedly used to pierce the dermis, leaving the ink embedded in the skin to create a design. Once a Tattoo is applied to the dermis it can only be removed via expensive laser surgery.

Tattooing is forbidden by the Bible in the Old Testament:

Ye shall not make any cuttings in your flesh for the dead, nor print any marks upon you: I am the LORD. Leviticus 19:28 (KJV)
