Answer:
Oh what besides screwing up the piercing, bleeding heavily and passing out during the piercing, choking to death, getting a secondary infection, hitting a vein in the tongue or a whole host of other horrible things that always happen when people attempt to do something a skilled professional should be doing. How about just common sense, you wouldn't try to remove a brain tumour would you? Leave the body piercing to trained professionals so you can enjoy the whole experience without having to worry about all the other stuff.
