Things I've learned from this film... (Spoilers)
1) If a convict says "You can't kill me," it means that he has supernatural abilities and can survive things such as being shot full of bullets, set on fire, and having a spike driven through the back of his skull.
2) If you tell a female agent, with a single year under her belt, that she is inexperienced, it means that you're a sexist.
3) If your cellmate attempts to sexually assault you, but you're able to fight him off, he'll be the closest thing to a friend that you have in prison and will never attempt any kind of retaliation, like say...when you're asleep.
4) If a man promises to kill you, kick his ass once and he and his friends will leave you alone.
5) The guards won't go down into the basement; but if you go there, you can get drugs, "women," and electrical equipment with which to kill the guards and make your escape. (Why is Van Damme the only inmate to ask Priest for a set of jumper cables?)
6) Prisoners have heroes who receive standing ovations upon entering the prison. They also have nicknames, like "The Sandman," and catchphrases such as "You can't kill me" and "bring me a dream."
7) Rather than kill you outright, the man whom you sent to prison will beat you up to send a message and wait until later to try and kill you.
8) Teenage nerds will attempt to seduce older, better looking, women after having been alone with them for three minutes.
9) Not only do evil politicians explain their plans before killing you, they'll also let you escape if their wife shows up and you briefly explain to her what is going on.
10) When the entire prison discovers that you're a cop, they'll form an angry mob and attempt to kill you. When the prison hero (see No. 6) attempts to kill you, said mob will stand back and watch the two of you fight while cheering on their hero.
11) Bigoted police can smell black people from a distance.
12) Being hit in the head with a wrench is enough to knock you down, but you can recover quickly enough.
13) Being thrown from a second storey catwalk onto concrete is no more painful than falling off of a bicycle.
14) If you're in a fight to the death and your opponent is down, it is wise to finish them off rather than stand posing and taunting in front of an open fire.
15) If you can defeat the prison hero, the previously hostile crowd will come to respect you, and let you pass, rather than kill you as they had previously intended. This rule extends to under cover police officers.
