dude, take advice from a black guy who's been on the inside twice.
1. act tough but not too tough. if you act too tough, everyone would want a piece of you
2. Don't talk about anime or manga. if you do, kiss your virginity and manhood good-bye.
3. Don't drop the soap -_-
4. Don't ask questions
5. Don't make eye contact with anyone. not even the warden
6. Don't talk to nobody
7. Always lift weighs like your a bad-ass

8. Never fumble infront of everyone
9. Fight somebody and beat them up under the first week you get it.
10. And last but not least, always keep something sharp in your pocket, you can make a shank from your tooth brush. oh and also, if anyone talks to you, just bone your face and slowly smoke a cigarette like a BOSS!!!
