Hey, let's make sure we're being polite to the other members, ok? It's okay to disagree with someone but it's important to express your opinion without resorting to insults.
oh my how this place has lost it's edge, I remember johanneschimpo (sp) just laying into people for stupid questions and it was hilarious, a good chunk of the fun reading the forum. you know some dick is gunna ask whats gunna happen I just took 5 grams of Tylenol and that's why you need that guy. just a thought.
on topic, I think it could be done with a 31g except the person would probably naturally slap at it like a mosquitoe bite or something and could lead to a bloody mess. I wouldn't advise trying.
