How do you convince your parents to let you get a body piercing?

I say try to figure out a good reason or make a deal or if you got good grades or something or say if you don't like it, i will take it out.

Sit down with your parents and talk about it with them, theres nothing wrong with a body piercing and if their point is that you wont be able to get a job later on, just tell them that if you do end up getting the piercing and a job you really want wont let you have one then you'll take it out.
