Well Little Johnny, according to the society you can be whatever you want to be, do whatever you want to do, but only if you believe in yourself and follow all the societies norms.
According to logic however the answer is no. You can pretend to be one though. I'm sure you can even get a suit and everything if you ask your parents nicely. (By nicely I mean clean the house and then ask. Works wonders I promise)
Why is the sink on fire?
