My wife is the most obsessive Bradbury fan who ever lived. Soon as I read this, I called her cell phone.

Me: In Fahrenheit 451, how does Montag know how to read?
Telcontar: ...He's a fireman.
Me: Yes, but reading is illegal.
Telcontar: HE LEARNED HOW. I don't know how, but obviously he did.

I got nothin'.... :D
