Anti-Endorphins. Puberty is the essence of feeling crap. It is also necessary to become a slave to the corporations, otherwise you'll be happy and oblivious all your life. This is why parents slip you a sedative and inject you with Puberty while you are sleeping when they think the time is right.
'Mmm...dear I think it's about time we inject our son with Puberty. He's old enough now.'
'Very good dear, I'll get some from the chemist tomorrow.'
'Don't get it cut, you don't want our son to have a small dick.'
'Oh come on dear, I can't afford the full dose and you know it!'
