How should I get my dad to give me a buzz cut?

ok im a 16 year old guy and i have longer hair combed forward. Its a pain in the @ss having long hair so i want to buzz it all off. but i look terrible with a buzz because i have a huge forehead, wide hairline, chubby face. but i dont really care about that though. But he wont give me one for that reason and even if someone else did it i would get in trouble. So what should i do?
